Subject: [PATCH] fix(install): alpha/beta self-update actually finds a real
 release now

ostp update -b alpha/-b beta (and install.sh --branch alpha/beta directly)
tried to download a GitHub Release literally tagged "alpha" or "beta".
No such tag has ever existed - gha.ps1 cuts a fresh VERSIONED tag on every
release (v0.4.2-beta.4, v0.4.3-alpha.2, ...) - so this always 404'd.

/releases/latest can't help either: it only ever returns the newest
non-prerelease (stable) tag, by GitHub's own definition, so it can never
surface an alpha/beta release even in principle.

Fix: for alpha/beta, query the full /releases list (returned newest-first)
and take the first tag_name containing "-alpha"/"-beta". Verified the
grep/sed extraction against a mock releases-list payload for both channels.
