fix(release): stamp the Arch package version, and ship the licence with it
pkgver sat at 0.0.18 while the tree was on 0.8.x, because the Arch package is
built by makepkg rather than the tauri bundler and set-version.sh never touched
it. makepkg produced a package whose version bore no relation to the source it
was built from — the exact failure that script exists to prevent, in the one
file it had missed.

Dev versions are converted to a pkgver Arch accepts: a hyphen separates pkgver
from pkgrel, so 0.9.0-3-gabc1234 becomes 0.9.0.r3.gabc1234. pkgrel resets to 1,
since a new upstream version restarts its packaging revisions.

Also installs LICENSE into /usr/share/licenses — MIT is not in Arch's common
licences, so a package under it has to carry the text.

Arch is not part of the automated release (build-release.yml covers linux,
windows and android), so v0.9.0 is unaffected; this applies to anyone building
the package by hand.

# Stamp the release version into every file that carries it.
#
# The git tag is the single source of truth for a release version. The versions
# committed in package.json / tauri.conf.json / Cargo.toml are a placeholder for
# dev builds; a tagged build overwrites all of them from the tag so they cannot
# disagree with each other or with the tag.
#
# Usage:
# ./scripts/set-version.sh 0.5.0 # explicit
# JELLYTAU_VERSION=0.5.0 ./scripts/set-version.sh
# ./scripts/set-version.sh # derive from git describe (dev builds)
#
# Accepts the version with or without a leading "v".
#
# Why a script and not four sed lines in CI: the version lived in four files and
# CI only ever rewrote one of them (tauri.conf.json), so a tagged release shipped
# a matching installer name and mismatched package metadata. Keeping the write in
# one place is what makes "the tag is authoritative" actually true.

# --- Android versionCode ----------------------------------------------------
# Only when the generated Android project exists (i.e. after `tauri android
# init`); on Linux/Windows jobs there is nothing to stamp.
#
# `tauri android init` derives a versionCode from the semver (0.0.15 -> 15).
# That is both tiny and NOT monotonic across our history: earlier local/dev
# builds shipped versionCode 1000 (from a 0.1.0 config), so a plain 15 is a
# *downgrade* and Android refuses the update.
#
# The floor has to clear the highest code actually in the field, which is not the
# same as the highest this formula has produced. v0.5.2 shipped versionCode
# **5002** under an earlier `minor*1000` scheme; the `minor*100` formula that
# replaced it yields only 1502 for that same version, and 1503 for 0.5.3 — so
# every 0.5.x release built from it was an un-installable downgrade for anyone
# already on v0.5.2, which is exactly the failure this block exists to prevent.
# The multipliers are widened and the floor raised past 5002 accordingly.
#
# code = 10000 + major*1000000 + minor*1000 + patch
# e.g. 0.0.14 -> 10014, 0.1.0 -> 11000, 0.5.3 -> 15003, 1.0.0 -> 1010000.
