Barrett Ruth a83f500144 feat(sync): auto-discover backends, per-backend auth, S3 backend ... Problem: sync backends were hardcoded in `SYNC_BACKENDS` list in `init.lua`, auth routed directly through `oauth.google_client`, and adding a non-OAuth backend required editing multiple files. Solution: replace hardcoded list with `discover_backends()` that globs `lua/pending/sync/*.lua` at runtime. Rewrite `M.auth()` to dispatch to per-backend `auth()` methods with `vim.ui.select` fallback. Add `lua/pending/sync/s3.lua` with push/pull/sync via AWS CLI, per-task merge by `_s3_sync_id` (UUID), and `pending.S3Config` type.		2026-03-08 19:50:58 -04:00
