N0zoM1z0 166dcd21d0 feat(javascript): recover readable modules with Wakaru (#848)
* feat(javascript): recover readable modules with Wakaru

Integrate pinned upstream source behind a typed optional recovery port,
preserve source identity and producer provenance, and publish verified
artifacts for existing JavaScript analysis through CLI and MCP.

Add focused real-tool CI with genuine bundler fixtures and bounded
resource, cancellation, cleanup, schema and packaged-artifact checks.

* fix(javascript): align recovery catalog and browser verification

Share canonical Wakaru provider identity, describe CLI mode options, and
format the new workflow test. Disconnect the real page transport after
its observation readiness progress instead of a fixed delay.

* refactor(javascript): consume the investigation evidence writer

Verify that the SDK recovery handler records complete Evidence through the newly shared investigation owner.

* chore(test): account for isolated recovery fixture compilers

* fix(javascript): validate recovery paths before acquiring the engine

Return field-specific invalid_format diagnostics for relative paths and verify compiled CLI/MCP parity even when the optional engine is unavailable.
