v0.49.4 - Reliable macOS Terminal Release Verification

Release date: 2026-07-26

This recovery patch prevents native terminal cleanup from hiding failures behind
an unbounded child-process wait and moves the exact macOS terminal scenario into
the pull-request candidate gate. It supersedes the incomplete v0.49.3 artifact
set while retaining its explicit session resume and fresh-start behavior.

Included

• Bounds Unix PTY cleanup with a SIGTERM grace period followed by SIGKILL,
  so a stopped or unresponsive child cannot hang the test process indefinitely.
• Adds an exact regression test that suspends the PTY child and proves cleanup
  returns within its termination budget.
• Emits native-terminal stage traces on every supported platform and runs the
  candidate and release probes with uncaptured output for actionable failures.
• Adds an exact macOS native-terminal candidate job before merge and tag
  publication, alongside the existing Windows candidate coverage.
• Preserves the v0.49.3 changes that start a fresh conversation by default,
  restore durable history through /resume, and isolate stale historical source
  pointers from unrelated prompts.

Compatibility and boundaries

• Existing public commands, model files, registries, and durable conversations
  remain compatible.
• Existing conversations remain available through /resume.
• GitHub Releases remains the only supported binary distribution channel.
