Add Google sign-in support for the Firebase sync account
One-tap sign-in for a fresh install, matching the pattern already shipped
in todo and crdt_sync_dart: openFirebaseWithGoogle() (google_platform.dart
abstracts the plugin's platform-channel dependence), isFirebaseConfigured()
that reads the stored session rather than trusting the account marker
alone (a marker with no live session is what made a synced phone read as
"not connected" for a full session), and storedAccount() for read-back
without the desktop-wrapper fallback that throws on Android.

Also generalizes crdt_sync_dart's ref pin to v0.10.0 and vendors the
override-guard script for the pre-commit hook already wired to it.

# Fail if a pubspec still overrides crdt_sync with a local path.
#
# The apps depend on crdt_sync as a *git dependency pinned to a tag*, so what
# CI builds is whatever that tag points at. A `dependency_overrides:` entry
# pointing at ~/utils/crdt_sync_dart is invaluable while developing an unreleased
# library change -- and catastrophic if it survives the commit: local tests go
# green against code CI has never seen, and the failure is silent in both
# directions.
#
# A comment in the pubspec asking someone to remember is deployment hygiene,
# not a fix. This is the gate.
#
# Usage: check_no_crdt_sync_override.sh [pubspec.yaml ...]
# With no arguments, checks ./pubspec.yaml.
