yuneng-jiang 45d41f4104 ci(release): create stable/X.Y.x line branch on X.Y.0 tags (#29457)
Each patch release currently spawns an ad-hoc patch/v1.84.N branch
that exists only to base the next patch's cherry-picks on, leaving
stale per-patch branches behind and making "what is queued for the
next 1.84.x" hard to answer. Switch to one long-lived line branch
per minor, stable/X.Y.x, created automatically the first time we
tag X.Y.0 on that minor, and tagged on for each subsequent patch.

The gate is ^v?(\d+)\.(\d+)\.0$, so rc / dev / nightly / .post /
patch tags all skip cleanly; the line branch is created exactly
once per minor. Existing release/<tag> behavior is untouched
(additive step), and RC patches keep their current patch/v1.87.0rcN
flow until that gets its own follow-up.
