Sync: Firebase only — drop the GitHub transport (kuhyx/syncs stays a frozen archive)

Browse Source 
The PC push aborted before it ever tried Firebase whenever the GitHub PAT
was missing ("Workouts NOT synced: no sync token"), so once the PAT was lost
this machine published nothing although Firebase was configured and live.
The phone has not written the GitHub repo since 2026-08-21.

- sync_client() / sync_client_or_reason(): firebase_client_for("screen_locker")
  only, proven with can_access_remote(), healed once from a sibling app's
  session, else a warning naming what will not sync (push AND pull) plus a
  recorded degraded source. No config -> warning, no fallback.
- _manual_push and scripts/tombstone_sync_record.py take their client from
  sync_client_or_reason(); the push result carries the reason.
- Deleted: read_sync_token, remote_client, the mirror client, _push_outcome
  (the half-landed-push case no longer exists), SYNC_TOKEN_FILE and
  SYNC_REPO_OWNER/NAME, the sync_token test fixture. Status backend is
  "firebase" or "none".
- crdt-sync pinned to v0.9.2 in pyproject, requirements.txt and
  install_systemd.sh (the installer still said v0.9.0).

kuhyx/syncs/screen-locker-sync is left untouched as an archive; no code
reads it.

## Status
**Superseded (2026-10-09): screen-locker sync is Firebase RTDB only.** The
phone stopped writing the GitHub repo on 2026-08-21, and from 2026-10-09 the
PC does not use it either: the push, `sync_client()` and
`scripts/tombstone_sync_record.py` all use `firebase_client_for("screen_locker")`,
and the sync_token / GitHub client / mirror code paths are deleted.
`kuhyx/syncs/screen-locker-sync` stays as a frozen archive that no code reads
and nothing deletes. The rest of this document is the historical design record.
**Blocked on Workstream D** (2026-07-04 user decision — see "Sequencing
decision" below). No code has been written for this workstream. The design
questions below (sync pattern, repo name, scope) have been pre-decided so the
