* fix(process): revalidate ownership before signaling
* fix(process): retain cleanup ownership until completion
* fix(process): keep omitted live descendants unresolved
A non-empty process table that omits a retained live PID cannot authorize a signal or certify cleanup. An empty table can still describe a token-verified owner.
* fix(process): read omitted Darwin run tokens by PID
A live identity that ps omitted was still validated through Darwin
environment(), which rejects any PID absent from a second process table.
Ask the native reader for that PID directly so the launch token can bind.

Keep a run-scoped evidence owner from acquisition through settlement and
cleanup retry. Bind token observations to native generations and retain
related generations and unresolved identity lookups across table omissions,
reparenting and process-group changes without treating PID hints as authority.
Use native effective UID facts for withholding decisions, corroborate Linux
procfs absence, and share the Linux stat parser with sampling and debugger
identity checks. Signal only after current token and group revalidation.
Complete swept cleanup across all groups with one bounded final family check;
retain unresolved owners and successful-peer completion across retries.
Validation: npm run check, docs:check and test discovery passed. Focused
ownership/consumer coverage totals 513 passed and 1 skipped across 35 files,
including the corrected Electron cancellation test rerun independently. Darwin helper compilation, real
owned Node child cleanup, CLI/MCP capture and retained cleanup retries ran.
Real Electron applications, native Linux races/PID reuse and Windows cleanup
were not qualified. The original Linux reports remain open for that work.
Fixes#5238
Refs #4322, #5206
Supervise sampler and ownership-query commands through physical exit on
cancellation. Share Darwin helper command ownership, reject new commands
after close starts, and drain admitted commands before removing the root.
Keep failed root cleanup retryable without rerunning completed queries.
