Validate final fork lifecycles and record review gates - #30

Completes the integration ledger and lifecycle diagnostic for the fork-only stack. The final soak checks golden scores through 100,000 ordinary calls, 1,000 alternating file/memory load-disposal cycles, and 100,000 managed bounded calls per runtime. The harness now discards results with Enum.each: an earlier collecting comprehension retained an accumulator and distorted memory observations. Temporary native lifetime counters confirmed reclamation and were removed; no production native implementation changed in this PR.

Corrected local results: bounded RSS ranged 102.8–104.2 MB on runtime 1.17.3 and 105.3–106.5 MB on 1.24.4; process counts stayed at 124 at every sample. Every call matched golden scores. These are synthetic CPU diagnostics, not leak guarantees for other models/providers. Exact byte counts and reproduction are in docs/integration.md.

The ledger records review order #2–#30, 216 suite checks (two optional ResNet cases excluded), constructor/environment/logging/bootstrap gates, scheduler measurements, fresh-VM upgrades, unsigned task commits, and ancestry-preserving merge guidance. API-25 per-run profiling and measurement-dependent GPU/NN primitives remain explicitly deferred; upstream/shared-package work stays outside scope.

Stacked on #29. Integration branch codex/ortex-integration combines the stack for source, all seven precompiled consumers, and complete package validation. The current combined stack additionally includes ownership fix #31; exact validation is recorded below. No release tag, upstream write, or Hex publication is part of this change.

Final combined validation is green at a4cef8490858d89b7827ef6e62ba652107434373 on codex/ortex-integration:

• Source matrix: API 17/runtime 1.17.3, API 17/runtime 1.24.4, API 24/runtime 1.24.4, and both Alpine architectures.
• Precompiled consumers and package: all seven CPU targets and complete checksum/package assembly passed with compiler execution forbidden during consumer testing. Release/tag-only jobs were intentionally skipped.
• Local suite: 218 checks passed on both runtimes; two optional external ResNet cases excluded. Long ordinary/load-disposal/bounded diagnostics checked every golden score, and post-reservation bounded soaks retained flat process counts and bounded sampled memory.

Review in stack order #2–#31. Preserve ancestry with merge commits, or rebase/retarget the remaining stack after squash/rebase merges. The worktree is clean. Fresh VM required for native resource upgrades. No upstream writes, release tags, or Hex publication were performed.
