perf(javascript): query selected source-to-bundle facts (#6128)

Select completed source-to-bundle mappings and candidates through the shared view owner, preserve reference-file provenance, and retain full Evidence. Reuse bounded JSON reading, heap admission, and cancellation before session writes.

Verified public Redux Toolkit source/map facts with an independent oracle, equivalent CLI/MCP workflows, focused negative controls, and complete CI/review. Historical paired SDK context estimates fall about 64%; timing/resource tradeoffs and final verification receipts are recorded without a general speedup or actual model-token claim.

Fixes #6112.
