v0.6.0

Changed

• Hooks now ship inside the plugin (hooks/hooks.json +
  hooks/never-stale-gate.js, resolved via ${CLAUDE_PLUGIN_ROOT}) and register
  machine-wide. /never-stale no longer writes any hook or script into your project —
  only a marker and a CLAUDE.md block.
• CLAUDE.md rules are now wrapped in <!-- never-stale:begin … --> /
  <!-- never-stale:end --> sentinels, so teardown is reliable even after you edit
  the text inside.

Added

• Per-project opt-in marker — .claude/never-stale.json (committed/team) or
  .claude/never-stale.local.json (gitignored/local, which overrides a committed
  marker and can veto it with "enabled": false").
• Git-bounded upward walk: the gate resolves the governing project by walking up
  from the launch directory to the nearest ancestor marker, bounded by the git repo
  root — so launching from a subdirectory still works and a marker outside the repo
  never governs it.
• /never-stale --list to enumerate every opted-in (and legacy) project on disk.
• Automatic migration of 0.5.0 installs when you re-run /never-stale.
• NEVER_STALE_DEBUG=1 diagnostic log in the OS temp directory.

Removed

• The project-local never-stale-reminder.js script and the per-project
  settings.json hooks (replaced by the plugin-owned, marker-gated hook). Existing
  0.5.0 projects keep working until migrated.
