fix(javascript): allow cancellation during semantic graph commitment (#1218)

Move whole-graph commitment and batched integrity checks into owned domain steps while retaining eager input capture, canonical IDs, full validation and completion-only immutable proofs.

Verified complete real Notion identity parity and actual stdio MCP cancellation, Evidence retention and connection reuse.
