deploy: treat an empty .last_good_tag the same as a missing one (#156)
cat file 2>/dev/null || echo latest only falls back when cat itself fails
(nonzero exit, i.e. the file is missing) -- a file that EXISTS but is EMPTY
makes cat succeed with empty output, so PREV_TAG became "" instead of
"latest". That "" failed the emptiness check further down and exited 1 --
AFTER git pull + docker compose up -d had already succeeded. Worse: exiting
there skips the Health check step (Gitea Actions doesn't run later steps
after a failure), and Health check is the ONLY step that ever writes a real
value to .last_good_tag. Self-perpetuating: once the file went empty, every
future deploy failed the same way forever, with the app itself deploying
fine underneath it every time (confirmed against run 611: deploy log shows
all three images pulled/recreated/started at 66bbf5b, and /health
self-reports that exact GIT_SHA, baked into the image at build time --
two independent signals, same commit).

${VAR:-default} covers empty and unset in one expansion, matching the
fallback behavior the surrounding comment already documented as intended.

# far (this one) left the leak unaddressed forever. That silently
# filled the disk to 100% over ~week of deploys (2026-09-12: 29G/29G
# used, 96 of 100 local images unreferenced, 23.76GB reclaimable) and
# took `git pull` itself down with "No space left on device" before
# the deploy could even determine a rollback target. Prune BEFORE
# doing anything else, not after: `docker image prune -af` only
# removes images with no container referencing them, so it can never
# touch what's currently running -- there is nothing here for a
# mid-flight deploy to lose. Warn-not-fail: a prune failure must not
# block a deploy that doesn't actually need the space this time.

# #13/#51 as if it were fixed. Moved to a standalone
# deploy-firestore-rules job below that runs on the Gitea runner
# itself (which always has node), so it no longer depends on
# anything being pre-installed on this VM.
# server-26#65: capture what is actually live BEFORE switching, so
# a bad deploy has something concrete to fall back to. This reads
# from a state file rather than re-deriving it from git log,
# because a PRIOR deploy could itself have failed and already
# rolled back to something older than HEAD~1 -- the file is only
# ever written by the Health check step below, after that step
