docs(installation): limit REA to one project or agent profile

Document existing Claude Code profile and per-project installation workflows, including scoped maintenance, backups, caller metadata and Windows commands. Clarify authentication storage and the filesystem/network restrictions required for enforced separation.

Validated 68 boundary tests, docs checks, formatting, typecheck/lint and two real REA setup dry-runs with zero applied actions or profile writes. Native Claude sessions, PowerShell execution and enforcement policies were not tested. Setup automation remains separate in #2187.

+## Who performs the action

+- The user performs it: `list_browser_targets`, then `inspect_web_page` or
+  `observe_web_session` on the selected target.
+- The agent must perform it: one `capture_browser_scenario` with declared
+  actions. Use connect mode with the loopback CDP endpoint and `target_id` for
+  an existing browser, or launch mode with a caller-selected executable for a
+  temporary profile. Connect mode first navigates the selected page to
+  `start_url`, which can clear unsaved form values and other temporary state.
+  Recreate the state needed for the investigation in the declared actions.
+  Connect mode leaves the external browser open; launch mode owns a temporary
+  browser and profile. Check `browser.cleanup` for the outcome.
+  Request only the DOM, accessibility, or network details needed for the question.
+  The default final capture contains the URL; step outcomes are reported separately.
+  Add a wait action for the expected page state before capturing it. Report that
+  REA performed the declared actions.
+
+Scenario network records have no request initiator stacks. For that evidence,
+use passive capture while the user performs the action. Listener source locations
+identify candidate handlers; they do not establish which script sent a particular
+request. Avoid overlapping passive capture and scenario actions on the same target.
+
+Focused follow-up tools:
+
+- `observe_web_execution`: execution coverage during a window; it resets
+  counters and temporarily disables optimization.
+- `inspect_web_event_listeners`: source locations for listeners registered
+  directly on the first CSS match, without dispatching an event.
+- `compare_web_captures`: two normalized passive captures or recorded scenarios.
+- `discover_webmcp_tools`: inspect page-declared WebMCP inventory; never invoke
+  the discovered tools.
+
 Use `reconcile_javascript_runtime` only after static application Evidence and
 passive browser/Electron Evidence exist. Prefer captured-source digest identity;
 report path/digest disagreement as a mismatch and preserve ambiguity. Explicit

+## Limit REA to one project or agent profile
+
+Setup registers REA for the whole client. For Claude Code it writes
+`mcpServers.rea` in `~/.claude.json` and installs the bundled skill under
+`~/.claude/skills`, so every project that Claude Code opens can call REA. To
+offer REA's tools only where they're wanted, use one of the routes below.
+
+Both routes control which sessions discover REA's MCP server and skill. They
+leave shell commands, filesystem access and network access available. An agent
+under the same OS account can run `rea` from `PATH` or `npx` and read other
+profiles and REA output. For clean-room separation, use an implementation
+environment with filesystem and network restrictions that prevent reading or
+fetching REA, the target and analysis output, including through shared
+installations and package registries. A separate account or container must
+enforce those restrictions.
+
+For Claude Code, check existing default-profile state before choosing either
+route. Setup is additive: a previous user-level REA registration and personal
+skill remain active in other projects. Back up the default configuration and
+REA skill first, then, with `CLAUDE_CONFIG_DIR` unset, remove the REA user
+registration with `claude mcp remove --scope user rea` and remove the known
+REA-installed `~/.claude/skills/reverse-engineer-anything` directory. Preserve
+unrelated registrations and skills. `rea uninstall` applies to other clients
+as well, so it is broader than this Claude-only migration.
+
+**A separate Claude Code profile.** Claude Code keeps settings, skills and session
+history under `CLAUDE_CONFIG_DIR`. Setup follows the same
+variable: it writes the registration to `$CLAUDE_CONFIG_DIR/.claude.json` and
+the skill to `$CLAUDE_CONFIG_DIR/skills`.
+
+```bash
+CLAUDE_CONFIG_DIR=~/.claude-rea npx rea-agents setup --client claude_code
+CLAUDE_CONFIG_DIR=~/.claude-rea claude
+```
+
+A new profile may need authentication. Console sign-ins without an API key are
+stored outside `CLAUDE_CONFIG_DIR`; see
+[Claude Code authentication](https://code.claude.com/docs/en/authentication#log-in-with-multiple-accounts).
+Sessions started without the variable use the default profile's registration,
+skill and history.
+
+Inline assignments apply only to that command. Keep the same prefix for every
+profile check, setup rerun, update, or removal; bare commands use the current
+environment and can otherwise inspect or recreate default-profile state:
+
+```bash
+CLAUDE_CONFIG_DIR=~/.claude-rea claude mcp list
+CLAUDE_CONFIG_DIR=~/.claude-rea npx rea-agents doctor --client claude_code --skill --json
+CLAUDE_CONFIG_DIR=~/.claude-rea npx -y rea-agents@latest setup --client claude_code --dry-run
+```
+
+After reviewing an update plan, rerun that same prefixed setup command without
+`--dry-run` and approve its exact changes. Profile removal likewise needs the
+prefix on `claude mcp remove --scope user rea` and any `rea uninstall` command;
+keep the broader client scope of uninstall in mind. Restart the selected
+profile after changing its pinned registration.
+
+`claude mcp remove` removes only the registration. To remove REA from this
+profile without running the broader uninstall flow, first back up the profile's
+REA-managed skill directory, then remove
+`$CLAUDE_CONFIG_DIR/skills/reverse-engineer-anything` as well. Keep other skills
+in the profile intact.
+
+The commands above use POSIX shell assignment syntax. In native Windows
+PowerShell, select the profile for the whole setup/launch/check session and
+restore the previous selection afterward:
+
+```powershell
+$previousClaudeConfigDir = $env:CLAUDE_CONFIG_DIR
+try {
+  $env:CLAUDE_CONFIG_DIR = Join-Path $HOME ".claude-rea"
+  npx rea-agents setup --client claude_code
+  claude mcp list
+  npx rea-agents doctor --client claude_code --skill --json
+  npx -y rea-agents@latest setup --client claude_code --dry-run
+  # After reviewing the plan, repeat setup without --dry-run and approve it.
+  claude
+  # Profile removal, when intended, also belongs inside this selected scope:
+  # claude mcp remove --scope user rea
+} finally {
+  if ($null -eq $previousClaudeConfigDir) {
+    Remove-Item Env:CLAUDE_CONFIG_DIR -ErrorAction SilentlyContinue
+  } else {
+    $env:CLAUDE_CONFIG_DIR = $previousClaudeConfigDir
+  }
+}
+```
+
+Use PowerShell for these Windows examples rather than pasting POSIX assignments
+into cmd.exe. Keep profile updates, readiness checks and removal inside the
+same selected environment; the `finally` block restores the previous profile
+or unsets the variable when it was absent.
+
+**One project.** Install without configuring Claude Code: use the curl
+installer's `--no-setup`, or run setup only for other clients. Then register
+REA from the project directory at Claude Code's local scope.
+
+This route uses the default Claude profile. Keep `CLAUDE_CONFIG_DIR` unset for
+the entire local lifecycle: registration, backup, listing, version replacement
+and removal. In POSIX shells run `unset CLAUDE_CONFIG_DIR`; in PowerShell run
+`Remove-Item Env:CLAUDE_CONFIG_DIR -ErrorAction SilentlyContinue` before these
+commands. Record an existing selection first if you intend to restore it after
+finishing. The configuration path below is the default profile's
+`~/.claude.json`; a different active profile uses its own config root instead.
+
+Register with the variable unset:
+
+<!-- x-release-please-start-version -->
+
+```bash
+claude mcp add --scope local rea -- npx -y rea-agents@6.4.0 mcp
+```
+
+On native Windows, use the same project directory and wrap the package-runner
+shim so the stdio client can launch it:
+
+```powershell
+claude mcp add --scope local rea -- cmd.exe /d /c npx -y rea-agents@6.4.0 mcp
+```
+
+<!-- x-release-please-end -->
+
+Local scope stores the entry under that directory's path in `~/.claude.json`,
+so other projects don't load it. This route doesn't install the bundled skill.
+Avoid `--scope project`, which writes `.mcp.json` into the repository where it
+can be committed or copied. `rea doctor` and `rea uninstall` read only the
+user-level entry, so they don't report or remove a local-scope registration;
+remove it with `claude mcp remove --scope local rea` from the same directory.
+`rea update` doesn't refresh it either, so it stays on the version it names.
+To move it to a newer release, first back up the project entry in
+`~/.claude.json` and record its environment and other metadata. In particular,
+preserve caller-selected overrides such as `REA_MCP_INPUT_SCHEMA_PROFILE` and
+`REA_MCP_MAX_RESPONSE_BYTES`. Run `claude mcp remove --scope local rea` from the
+same directory, then recreate it with the platform-appropriate command above
+and the new version. Reapply every recorded environment value with Claude
+Code's `mcp add --env NAME=value` options and restore any other retained entry
+metadata before restarting the project session. Removal and re-addition do not
+preserve these values automatically. Running setup for Claude Code instead
+would add a user-level entry for every project.
+
+Check the separate profile with the prefixed `claude mcp list` above and compare
+with the default profile with `CLAUDE_CONFIG_DIR` unset. For local scope, run
+`claude mcp list` from the selected project and again from another project.
