Release 0.0.7: user-local installer + self-update apply

- install.sh: no-root user-local install (private venv + ~/.local/bin launchers
  + desktop entry); --ref <tag> to install a specific release, --uninstall to
  remove; auto-installs the python3-venv prerequisite with consent
- packaging/make-run.sh: build a self-extracting .run installer (makeself)
  bundling the wheel + install.sh; release workflow builds and attaches it
- M13 self-update apply: `rigdoctor update` runs an authenticated pip upgrade
  (rigdoctor[gui] @ git+https://oauth2:<token>@...@<tag>), token scrubbed; GUI
  sidebar "Update to v…" button applies it and prompts to restart
- version 0.0.7, CHANGELOG, docs (M9/M13, ROADMAP, README install section)

+## [0.0.7] - 2026-05-21
+### Added
+- **User-local installer** `install.sh` (no root): creates a private venv, links
+  `rigdoctor`/`rigdoctor-gui` into `~/.local/bin`, and adds a desktop entry. Re-run to
+  upgrade; `--uninstall` to remove.
+- **Self-extracting `.run` installer** via `packaging/make-run.sh` (makeself) — one
+  download-and-run executable bundling the wheel + `install.sh`; built and attached to each
+  release by CI.
+- **Self-update apply (M13)**: `rigdoctor update` now installs the newer version via
+  authenticated pip (`rigdoctor[gui] @ git+https://oauth2:<token>@…@<tag>`); the GUI sidebar
+  "Update to v…" button applies it and prompts to restart. Token is scrubbed from output.

+## [0.0.6] - 2026-05-21
+### Added
+- **Token-gated updates (M13)**: store a Gitea Personal Access Token, **encrypted in the OS
+  keyring** (Secret Service / GNOME Keyring via `secret-tool`) with a 0600-file fallback.
+  `rigdoctor login` / `logout` / `update [--check]`; GUI **Setup → Update access** panel

+- `libsecret-tools` added to the installer catalog (enables encrypted token storage).
+### Changed

+## Install (user-local, no root)
+
+RigDoctor installs into a private venv under `~/.local` — no root, self-updating:
+
+```bash
+./install.sh                 # from a source checkout or the self-extracting .run
+./install.sh --ref v0.0.6    # install a specific released tag (needs a token)
+./install.sh --uninstall     # remove it
+```
+
+This adds `rigdoctor` / `rigdoctor-gui` to `~/.local/bin` and a desktop entry. Each release
+also ships a one-file **`.run`** installer (download, `chmod +x`, run). Updates are gated to
+accounts on the Git server (a Personal Access Token); save one via the GUI **Setup → Update
+access** panel or `rigdoctor login`, then `rigdoctor update` (or the sidebar button).

 RigDoctor should **check for a newer version on launch and self-update** (new module **M13**).
-**Mechanism (chosen): user-local, no-root self-update from the public repo.**
+**Mechanism (revised): user-local, no-root self-update over authenticated HTTP (token).**
+*Why revised:* the Gitea instance requires sign-in for **all** anonymous access (repo page,
+releases feed, raw, API all 303/403 anonymously), so the original "public HTTP" plan can't
+work. Updates are therefore **gated to people with an account on the Gitea server**, which is
+desirable — access control is delegated to Gitea.
+- *Auth:* each user creates a **Personal Access Token** (scope `read:repository`); RigDoctor
+  stores it at `~/.config/rigdoctor/token` (mode 0600) or reads `RIGDOCTOR_TOKEN`. Requests
+  send `Authorization: token <PAT>`. Finer access = repo visibility/collaborators on Gitea.
+- *Check:* `GET /api/v1/repos/jessey/rigdoctor/releases/latest` with the token; compare tags.
+- *Apply:* `pip install --upgrade "git+https://oauth2:<token>@…/rigdoctor.git@<tag>"` into the
+  user-local venv, then restart (incl. the daemon). No root.
+- *States surfaced:* no-token → "connect to update server"; auth error → "access denied";
+  newer → "Update to v…"; else "up-to-date".
+- *Original (now-superseded) plan was anonymous public HTTP:*
 - *Install model (D8 revised):* primary install is **user-local** (`~/.local`), so the running
   app can replace its own files and update with **no apt, no root, no password prompt**.
 - *Check:* on launch, query the **public Gitea releases API**
