Two fixes for the release script:
**1. Branch regex cleanup** — Simplified to only match `release/X.Y`.
Removed
support for `release/X.Y.Z` and `release/X.Y-rc.N` branch formats. RCs
are
now tagged from main (not from release branches), and the three-segment
`release/X.Y.Z` format will not be used going forward.
**2. Changelog range for first release on a new minor** — When no tags
match
the branch's major.minor, the commit range fell back to `HEAD` (entire
git
history, ~13k lines of changelog). Now computes `git merge-base` with
the
previous minor's release branch (e.g. `origin/release/2.32`) as the
changelog
starting point. This works even when that branch has no tags pushed yet.
Falls
back to the latest reachable tag from a previous minor if the branch
doesn't
exist.
