## Why PR #26797 was accidentally merged into the stale `graphite-base/26797` branch instead of `main` (Graphite picked the wrong base), so its changes never landed on `main`. This PR re-lands that work as a clean cherry-pick onto the current `main`. ## What Adds a `WatchAIProviders` streaming RPC to the `ProviderConfigurator` service so a running standalone AI Gateway refetches its provider set when the provider configuration changes. The server subscribes to `AIProvidersChangedChannel` (published by the provider CRUD endpoints) and forwards each event as a payload-free signal, plus one signal on subscribe; the gateway calls `GetAIProviders` on each signal to rebuild its pool. The aibridged API is bumped to v1.2. Env-seeded providers don't need a signal: seeding finishes before coderd serves the gateway connection, so the gateway's initial fetch already reflects the seeded set. ## For reviewers The change is split into two commits to make review easy: 1. **`feat: synchronise provider changes with WatchAIProviders`** is a faithful cherry-pick of #26797, identical to the originally reviewed PR. It is committed without pre-commit hooks because it does not build against current `main` on its own. 2. **`fix: resolve cherry-pick conflicts against main`** contains only the deltas needed to re-land on current `main`, and passes the full pre-commit suite: - `coderd/aibridged/proto/aibridged.pb.go` regenerated via the proto make target (the cherry-picked copy was generated against the older proto). - `enterprise/cli/aigatewaystart.go` import block unioned; `main` added `os` and `strings` while the PR added `sync`. - Three `aibridgedserver.NewServer` test call sites that landed on `main` after the original branch diverged now pass the new `pubsub` argument.
