fix(ci): delete the per-branch push triggers instead of adding feat/** to them

The tracked next-step said "align gate.yml's push trigger with this repo's feat/**
prefix". Doing that literally would have made things worse, so this does the opposite.

act_runner runs at capacity 1. A branch push and its PR fire the SAME gate over the SAME
tree, and the redundant run SERIALISES AHEAD of the PR run -- doubling the wall clock on
the one result that gates the merge. Adding another prefix widens that, it does not fix
it. infra/plex/claim-ship.sh currently has to pick a feat/ branch name specifically to
DODGE this, during a loop that is racing a short-lived token.

The prefix list also silently failed to match this repo's own convention: branches here
are feat/**, which was absent, so the "fast feedback" never fired for the most common
prefix. Nobody noticed for a month because the only symptom of a wrong entry is a MISSING
run. Any hand-maintained prefix list has that failure mode. Deleting the list removes the
whole class rather than correcting one entry.

It was redundant anyway: CLAUDE.md already requires ./ci/gate.sh in the pinned toolbox
before pushing (74s locally), and the PR gate re-runs it authoritatively.

push: [main] is KEPT -- post-merge main must still be verified, and it is the only run for
which no PR context exists.

FOLLOW-UP once this and #5 are both merged: the feat/ rationale in
infra/plex/claim-ship.sh becomes obsolete and its comment should be trimmed. The script
keeps working either way.
