Release 0.0.2: M3 logger (CLI + GUI), GUI-first, CI release workflow

Crash-capture logger (M3):
- crash-safe JSONL (fsync per sample), size-based rotation, GPU-lost/recovered
  markers, atomic status file
- CLI: record run/start/stop/status/report (run = systemd-ready entrypoint)
- shared core.reccontrol so CLI + GUI drive the same recorder
- crashlog tests (writer, rotation, reader, summary, recorder)

GUI:
- Recording/Logs page: start/stop/interval controls, live status, post-crash report
- shared render helpers (format_raw/headline, render_summary)

Docs/decisions:
- GUI-first (D17); CLI keeps full parity
- D8 revised: user-local self-updating install primary, .deb optional
- planned: M12 session sharing (D16), M13 no-root auto-update from public repo (D18)
- versioning + CHANGELOG convention (D19)

Infra:
- .gitea/workflows/release.yml: build wheel+sdist and publish a Gitea release
  v<version> on push to main
- align version to the 0.0.x release line; bump to 0.0.2

+# Changelog
+
+All notable changes to RigDoctor are recorded here. Format follows
+[Keep a Changelog](https://keepachangelog.com/); versioning is SemVer-style
+(`MAJOR.MINOR.PATCH`, pre-1.0). `__version__` and `pyproject.toml` must match the git
+release tag (so the auto-updater, D18, can compare versions).

+## [0.0.2] - 2026-05-21
+### Added
+- **M3 crash-capture logger**: crash-safe JSONL (`fsync` per sample), size-based rotation,
+  GPU-lost/recovered event markers, atomic status file; `rigdoctor record run|start|stop|
+  status|report` (foreground `run` is the systemd-ready entrypoint).
+- **GUI Recording/Logs page** (M10): start/stop/interval controls, live status, and the
+  post-crash report — driving the same recorder via shared `core.reccontrol`.
+- Shared render helpers (`format_raw`, `format_headline`, `render_summary`) used by CLI + GUI.
+- Tests for the crash log (writer, rotation, reader, summary, recorder).
+- **Gitea Actions release workflow** (`.gitea/workflows/release.yml`): on push to `main`,
+  builds wheel + sdist and publishes a Gitea release `v<version>` with the artifacts.
+### Changed
+- **GUI-first** emphasis (D17): docs reframed; the CLI keeps full parity for headless/SSH.
+- CPU core temperatures ordered (package, then core 0, 4, 8, …) at the source — fixes the
+  CLI ordering too.
+- Distribution revised (D8): **user-local self-updating install** is primary, `.deb` optional.
+### Planned (docs only)
+- M12 session sharing / remote assist (D16); M13 no-root auto-update from the public repo
+  (D18); versioning/changelog convention (D19).
+
+## [0.0.1] - 2026-05-21
+### Added
+- Initial release: planning docs and decisions (D1–D15); **M1 sensor core** (NVIDIA GPU via
+  nvidia-smi, CPU via hwmon, memory + DDR5 SPD temps, NVMe); CLI (`snapshot`, `monitor`,
+  `sources`); and the **M10 desktop GUI** — dark dashboard with circular gauges and
+  collapsible, temperature-colored cards.
