* fix(javascript): match unchanged module exports across application versions
An export binding's identity is keyed within its whole application root (container_sha256), so it changed whenever any sibling file changed, and no match tier paired export nodes: every export of an unchanged file was reported removed and added, and its module fell to unknown. The exact module-source-digest tier now also pairs an export binding by its own file's bytes (identity artifact_sha256) and exported name, as it already pairs a source module by source_sha256. Exports of edited files stay unmatched.
* style(javascript): format the version-matching export test

Classify wholly unknown or unavailable node observations at the version-item owner and retain their limitations across matched and unmatched comparisons. Preserve positive mixed observations and genuine additions/removals.
Validated source regressions and public CLI/stdout MCP workflows in the 103-test focused gate; typecheck and lint pass. Fixes#5534.
Keep positive topology differences separate from unpaired neighbor identity. Preserve exact content pairing and source observations, report unresolved relationships without inventing incomplete inventory, and omit comparison edges when no substantive difference was observed.
Validated with 45 focused domain/CLI/MCP tests, nine expanded domain controls, check:fast, and docs:check. Clean baseline fails seven controls and passes two positive controls. Controlled static fixtures only; no target execution or large-bundle profiling.

Retain bigint/directive values, assignment operators, fixed public keys and
execution-affecting syntax flags in v3. Preserve local/private binding renames
and isolate structural matching by algorithm version. Remove the redundant
test grouping and document structural matching as heuristic evidence.
Validated AST, worker admission, archived-version matching, reconstruction and
public CLI comparisons. Auto-accessors are tested at the AST boundary because
the production JavaScript parser does not enable their Babel plugin.

perf(javascript): avoid quadratic temporary matching state
Repeated source groups can allocate candidates that later identity matches
discard. Retain the original ambiguous groups until all tiers finish, expand
only unmatched survivors, and append to locally owned key buckets in place.
Constraint: Preserve matching priority, full ambiguity, and public output.
Directive: Do not re-match residual groups that become unique after later tiers.
Tested: 59 relevant tests, npm run check, and test discovery on current main.
Tested: CLI benchmarks and full-suite failure comparison on the recorded base.
Not-tested: Full suite on the updated main; native Linux and Windows workflows.
