Merge origin/main into deferred OpenCode restart branch.

Resolve ProvidersPage and lifecycle conflicts with custom providers and
AppImage ARGV0 stripping. Address review follow-ups: OAuth index helper +
tests, single auth-methods load trigger, shared Google env-alias module with
VS Code parity coverage, and deferred restart for custom provider upsert.
