feat: in-app uninstaller, changelog viewer, version automation (0.1.0)

First milestone release — a complete, installable, self-updating RigDoctor:
live monitoring, crash capture + health report, desktop GUI, user-local
install/uninstall, and token-gated self-update with real release notes.

- feat(gui): in-app uninstaller — Setup "Uninstall RigDoctor" button and
  `rigdoctor uninstall [--purge]`; removes venv/launchers/desktop entry
  (detached so it can delete its own venv), with optional purge of
  settings/token/logs (core/uninstall.py)
- feat(gui): in-app changelog — sidebar "Changelog" link listing release
  history fetched from the update server (updates.list_releases)
- chore: versioning rules + automation (D21) — git-cliff --bumped-version,
  packaging/bump.sh, cliff.toml [bump] (pre-1.0: breaking -> minor)
- chore(release): stamp 0.1.0; milestone policy recorded in D19

+_First milestone release — a complete, installable, self-updating RigDoctor: live monitoring,
+crash capture + health report, desktop GUI, user-local install/uninstall, and updates._
+### Added
+- **In-app uninstaller**: "Uninstall RigDoctor" button on the Setup page (and
+  `rigdoctor uninstall [--purge]`) — removes the venv, launchers, and desktop entry, with an
+  option to also wipe settings/token/logs. Runs detached so it can delete its own venv.
+- **In-app changelog**: a "Changelog" link in the sidebar opens the release history (tags +
+  notes) fetched from the update server.

 ## [0.0.10] - 2026-05-21
 ### Added
 - **"Restart now" button** after a successful in-app update — relaunches RigDoctor for you

 update mechanism (APT repo vs. self-installed `.deb`).
