v1.0.0

Added

• Tool window listing every GitHub pull request review thread for the checked-out branch, with the
  repository and PR detected from the git remote and branch, and a manual PR-number override that is
  remembered per branch.
• Filters for resolved/unresolved, replied/not replied/replied by me/awaiting my reply, outdated,
  author (multi-select), file path and free text — all applied locally, with debounced text input.
• Sorting by created date, last activity, file path or line, ascending or descending, with a stable
  path-then-line secondary order.
• Detail pane showing the full thread with Markdown-rendered comments, the diff-hunk snapshot as the
  code looked when the comment was written, and the current state of that line in the working tree.
• Drift-corrected line mapping with an honest state chip (Current, Moved, Changed since comment,
  Line removed, File deleted) and navigation that refuses to guess when the line is gone.
• Inline replies (Cmd/Ctrl+Enter), Reply and Resolve, and resolve/unresolve from the detail pane,
  the list context menu or a keystroke — all optimistic, with rollback and a Retry action on failure.
• Manual refresh (toolbar, F5) and auto-refresh on a timer while the tool window is visible, preserving
  selection, scroll position and unsent reply drafts, and guarded by a cheap updatedAt pre-check.
• Settings page under Tools with the GitHub host, optional REST/GraphQL URL overrides, a personal
  access token stored in PasswordSafe, a Test connection button, and the auto-refresh interval.
