fix(javascript): bound semantic unknown retention at projection

Admit unknowns before canonical construction and provenance interning. Offer independent per-file and application capacities through CLI, Evidence and the owned analysis worker, and reject over-allocation during streamed decoding.

Report examined omitted emission occurrences by family and reason without retaining discarded identities. Preserve omission-free graph identities and distinguish node truncation from overall partial coverage.

Fixes #4797
