What changed and why

Add a process profiler and recorded VM/browser performance measurements, including stopped-process rejection and live lag diagnostics. The report incorporates the native OpenGL result from the preceding graphics PR and describes measurement limits. Tests cover the profiler's accounting and validation behavior.

Release split 12/15 from prepare-0.5.0 at 7240777, including main's audio fix at 226ca68. This PR follows preceding PR in the release stack and targets main. Merge the stack in order with merge commits; squash/rebase merging requires restacking the remaining PRs. The complete stack plus package-lock PR #292 reproduces the original release tree exactly.

Testing

  • git diff --check codex/release-050-graphics..HEAD: passed.
  • python3 tests/test-profile-process.py: passed.

The assembled original release tree passed make test TEST_JOBS=2 on macOS 27.0.1 / Apple Silicon, including 402 Swift tests. Pinned-source checks use Omarchy v4.0.4 at c668141e9c42b13c80c9ca4ea108e11708c5e8a5. Extraction and testing used an isolated worktree; the original checkout/build was untouched.

Guest/runtime component builds and app/guest visual checks were not rerun during extraction. CI builds and macOS 15/26 results remain pending.
