Barrett Ruth 25c8bd4eb0 refactor(sync): extract shared OAuth into oauth.lua ... Problem: `gcal.lua` and `gtasks.lua` duplicated ~250 lines of identical OAuth code (token management, PKCE flow, credential loading, curl helpers, url encoding). Solution: Extract a shared `OAuthClient` metatable in `oauth.lua` with module-level utilities and instance methods. Both backends now delegate all OAuth to `oauth.new()`. Skip `oauth` in `health.lua` backend discovery by checking for a `name` field.		2026-03-05 01:17:47 -05:00
