* fix(ci): stop hourly versions dropping below a tagged or already-shipped build
Hourly/daily/adhoc based their X.Y.Z on GitHub releases, not git tags. When
v1.4.202 was tagged and then its GitHub release vanished, the next hourlies
shipped as 1.4.202-hourly — below both stable 1.4.202 and the 1.4.203-hourly
builds already installed, so electron-updater stopped offering updates.
Read main's v* tags and already-published channel tags instead.
* docs(ci): record that 1.4.202's release was unpublished for a bug
The leftover tag is what hourly must still honor; this was not a failed cut.
The adhoc mac and dev-channel Windows builds vet the requested ref by
mirroring every branch and tag of this repo into a scratch bare repo and
proving the commit is reachable. Both runner disks are case-insensitive,
and the repo now has two branches differing only in casing, so the files
backend refuses the fetch outright — the whole job dies before checkout.
reftable keys refs in a table rather than as file paths, so both refs
store and every ref stays in the reachability set.
