The launcher from Hookshot's 3.0 launcher, renamed to Longshot and made a clean start at
Longshot's v3.0.0: no hand-over from a 2.x install, nothing read of Hookshot's settings,
folders, channels or versions.

- Three channels, stable, rc and nightly, for Longshot's builds and for the launcher
  itself, chosen in the window. Longshot's numbers start at v3.0.0, the launcher's at
  v1.0.0.
- Longshot's builder installed per version from its signed release (ECDSA P-256 over the
  release file, SHA-256 of every list and part), and moved to the channel's newest.
- Its own updates from its own signed releases: downloaded, checked, started with
  --self-check, swapped in one rename (Windows: aside, then in), --rollback to undo.
- The Hookshot save importer: finds Hookshot's saves, checks them, copies them (never
  moves), asks before replacing a Longshot save and backs it up first.
- CI and releases on Forgejo Actions (.forgejo/workflows), scripts/package.sh and
  scripts/release.py, docs/releases.md, docs/hookshot-saves.md, AGENTS.md and
  CONTRIBUTING.md.
