fix(javascript): keep unselected sources out of cancellation failures

With source_paths, the analysis loop checked cancellation before it
recognized an outside-analysis-scope file. Cancellation arriving after the
last selected source therefore recorded the next unselected file as a
cancelled analysis failure, and the completion loop skipped it as already
analyzed.

Give out-of-selection classification one owner, used by the loop, the
interruption handler and the completion loop. The cancellation is still
reported as the interruption.

+### Soft-float prototype
+
+Ghidra's MIPS32 compiler specifications model hard-float o32 only: a typed
+`float` or `double` parameter is bound to `$f12`/`$f14` and returned in `$f0`.
+Soft-float o32 passes those values in integer registers and stack slots, so a
+typed prototype (for example from DWARF) would make the decompiler read FPU
+registers the code never writes and drop the real dataflow. That applies to
+functions, external functions and indirect calls through typed function
+pointers alike.
+
+For soft-float targets REA commits
+`mips_soft_float_storage: o32-soft-float-prototype-v1` in the analysis profile
+and runs `ReaGhidraMipsSoftFloat.java` after auto-analysis. The script encodes
+the program's own default o32 prototype, removes its floating-point parameter
+and return entries and the rules that consume floating-point storage, and
+installs the result as the program-specific `__rea_soft_float` prototype through
+a Ghidra specification extension. Deriving it keeps the byte-order-specific
+aggregate rules and the hidden struct-return pointer. The script then assigns
+that prototype, with dynamic storage, to every non-thunk function and external
+function, and to every function-pointer definition, whose declared types use
+`float` or `double`. Thunks follow their targets. Types are kept.
+
+The script fails, and writes no report, if the derived prototype still places a
+float in an FPU register or any reassigned function does. It records the
+function and definition counts last; REA requires that report exactly when the
+profile commits the policy and refuses the session otherwise, before serving any
+operation. Session Evidence carries the policy and counts as limitations.
+Callables without typed float signatures keep Ghidra's default prototype, under
+which Ghidra already infers integer-register parameters. Hard-float profiles do
+not gain the policy, so their digests are unchanged.
+
+### Relocatable objects
+
+`ET_REL` objects, such as Linux kernel modules (`.ko`), are imported by Ghidra's
+ELF loader, which assigns each allocated section an analysis address and applies
+the object's REL relocations there. Undefined symbols are placed in Ghidra's
+`EXTERNAL` block: a thunk for code, a label for data. These addresses are
+analysis coordinates, not the addresses a kernel or linker would choose, and
+session Evidence says so. `inspect_native_load_image` reports each relocation
+with Ghidra's status; HI16 entries report `PARTIAL` because Ghidra applies them
+together with their paired LO16. Relocatable targets commit
+`mips_support_lane: elf32-rel-o32-arch32r2-standard-v1`, separate from the
+executable lane, whose identity executable targets keep. Kernel modules are
+usually soft-float and therefore also use the soft-float storage policy.

+Both profiles support procedure/string inventory and literal or regex search, procedure resolution, pseudocode, assembly, raw function instructions, resolved callees, incoming address references, and a function dossier. Inventories and modern pseudocode/assembly follow upstream pagination. Upstream limits on modern xrefs and callees are retained as explicit truncation limitations. In the modern headless profile, targets that are not proven x86-only use processor-neutral `callgraph` edges instead of the x86 instruction checks in upstream `callees` (mrexodia/ida-pro-mcp#549). REA requests depth zero: the pinned upstream emits the root's outgoing edges without scanning child functions, then REA batches function-name lookup for those addresses. The graph covers recognized function destinations only; imports and other non-function targets remain unknown. A server without `callgraph` returns an empty relationship list with an explicit coverage limitation. Graph and path workflows retain those limitations alongside observed edges. A failed or inconsistent graph reply remains an error. A transport-level truncated preview is rejected rather than reported as complete evidence; the error preserves upstream retrieval guidance.
 
 The legacy profile additionally supports direct callers. Its producer may report call-site or interior addresses; REA resolves the reported function symbol to its canonical entry. The modern profile does not prove direct callers from its code/data xref labels, so that capability is unavailable and the dossier marks it unknown.
