build: make the git tag the single source of truth for the version (DR-153)

Browse Source

The version lived in four files — package.json, tauri.conf.json, Cargo.toml and
Cargo.lock — that had to be hand-edited in lockstep, and the release workflow
rewrote exactly one of them. A tagged build therefore produced an installer
named for the tag wrapped around package metadata naming the previous release,
and the Linux job, which had no version step at all, shipped whatever happened
to be committed.

scripts/set-version.sh now writes all four from one argument and is the only
thing that does. Every release job calls it with the tag, including the Linux
job that was missing one. The committed versions become a placeholder for dev
builds rather than something to maintain by hand.

The Android versionCode moves into the same script, unchanged in formula
(1000 + major*10000 + minor*100 + patch). It stays inline-documented because the
reasoning is not obvious: builds already in the field shipped code 1000, and
Android refuses an update whose code is lower than the installed one, so a
formula that can emit a smaller number for a newer release bricks updates
irreversibly. UT-150 asserts that property directly — monotonic across an
upgrade sequence, and always above the floor.

Two edge cases the previous inline version got wrong:

- A prerelease tag (v0.6.0-rc1) made $(( 0-rc1 )) abort the step under set -e.
  The suffix is stripped before the arithmetic; the manifests keep it.
- CI passes "${GITHUB_REF#refs/tags/}" unconditionally, which on a branch build
  is still a full ref. That reached the validator verbatim and would have failed
  every untagged Android build; a non-tag ref now falls back to git describe.
