feat(javascript): add filtered retained module reference views

Expose filtered canonical module identities, retained source-range counts and mixed support through the existing shared CLI/MCP analysis view. Preserve full-item access, source selection, provenance and partial coverage while allocating only the selected page.

Verify exact facts and CLI/MCP identity on shipped Obsidian, record complete-task BPE/resource measurements and reuse owned-process supervision for optional tokenizer cleanup.

Fixes #4092
Part of #4027; decision #4091.
