Make the Play listing publish manual-only

[patrickrb]

What

A merge to main no longer touches Google Play in any way.

android.yml already uploaded no AAB on a main push (#794) — play-listings.yml was the last Play-touching thing left on that path: a main push touching fastlane/metadata/android/** published the changed locales to the store as a side effect of the promotion. This drops that trigger.

After this

Event	What happens
PR touching listing metadata	validate only (completeness + Play character limits) — unchanged
push to dev / staging / main	nothing — no listing publish
Actions → "Play store listings" → Run workflow	dry-run (default, read-only) / check-permissions / publish
python .github/scripts/publish_listings.py locally	the same publish, run when you're ready

So staging → main now cuts the android-v<x.y.z> tag + GitHub Release and the desktop-v* release, and stops there. Both the app binary and the store copy are shipped deliberately, by hand.

Also: MODE now falls back to the read-only dry-run rather than publish, so a mode that somehow arrives empty sends nothing to Play.

Tests

No new code path — the change is workflow triggers plus docs. The 135 publish_listings unit tests pass unchanged (python -m unittest discover -s .github/scripts), and the workflow still parses with only pull_request + workflow_dispatch triggers.

Docs updated: docs/release-pipeline.md (branch lifecycle + Store listings section) and docs/store-listings.md (Publishing section).
