feat(web): check that a provider secret reference resolves

[yordis]

• A secret reference that is misspelled, points at a locked vault, or names a provider the server cannot reach only surfaces once the agent starts with the variable missing. Nothing in Settings tells the user whether the reference works before they save it.
• Each secret variable now has a check button that reads the reference through its store on the server and reports resolved or failed, with the store's own error text, so a broken reference is caught while the user is still editing it.
• The check tests the draft as written, not the saved value, because the common case is fixing a reference and wanting to know it works before saving.
• The server never returns the secret value. A successful check primes the resolver cache so the next provider start does not prompt again.
• The method requires the same settings write grant as saving a provider, since it lets a client probe which references a server can read.

PR Summary

Medium Risk
Adds a settings-gated RPC that probes secret backends from the server; successful checks cache credentials, but scope matches settings write and values are not returned to the client.

Overview
Adds a Settings “check secret” flow so users can validate provider secret references (1Password, OpenBao, AWS) before saving, without starting an agent.

Server: New server.checkSecretSource RPC returns Resolved or Failed with store error text and never exposes the secret value. ProviderSecretResolver.check performs a fresh read (bypassing cache), primes the resolver cache on success, and is gated like other settings writes (AuthSettingsWriteScope). Secret-store reads in ProviderSecretResolverLive now use a SecretRead result type so failures carry actionable detail strings (CLI stderr, OpenBao errors, timeouts) shared by check and resolve.

Web: ProviderEnvironmentSection shows a per-row check control (spinner / success / error tooltip) against the draft source when environmentId is available; wired through serverEnvironment.checkSecretSource.

Docs and tests cover the RPC, resolver behavior, UI, and permissions.

📝 Walkthrough

The change adds a permission-guarded RPC to check provider secret sources. The server reports resolution results and failure details, and provider settings display the check status for the current secret source.

Changes: Secret source check flow

Layer / File(s)	Summary
RPC contract and permission packages/contracts/src/secretProvider.ts, packages/contracts/src/rpc.ts, packages/contracts/src/clientRpcPermissions.ts, packages/client-runtime/src/state/server.ts, packages/client-runtime/src/state/commandPermissions.test.ts	Adds the result schema and RPC method, assigns the settings-write scope, and exposes the client command. The permission test checks authorization for the destination environment.
Secret read results and resolver check apps/server/src/provider/ProviderSecretResolver.ts, apps/server/src/provider/ProviderSecretResolverLive.ts, apps/server/src/provider/ProviderSecretResolverLive.test.ts, apps/server/src/provider/ProviderRegistry.test.ts, apps/server/src/orchestration-v2/ProviderAdapterRegistry.test.ts	The resolver returns detailed read outcomes and implements checks that cache successful values without returning the secret. Tests cover success, failure details, and cache priming; resolver test doubles implement the new method.
Server RPC handling and instrumentation apps/server/src/ws.ts, apps/server/src/observability/RpcInstrumentation.ts	The WebSocket handler delegates checks to the resolver. Instrumentation maps the method to the server aggregate.
Provider settings check UI apps/web/src/components/settings/ProviderInstanceCard.tsx, apps/web/src/components/settings/AddProviderInstanceDialog.tsx, apps/web/src/components/settings/ProviderSettingsPanel.environment.browser.test.tsx, docs/fork/0033-secret-providers-have-names.md, docs/user/provider-secrets.md	Provider settings pass the environment ID and show check status for the current secret source. The browser test covers failed and resolved results. Documentation describes checking a reference, including unsaved edits.

The secret check remains usable, but OpenBao errors should be replaced with safe log metadata before merge or accepted as a bounded follow-up.

Full details: Description check

Explanation

The description clearly explains the problem, behavior, security constraint, permission requirement, and includes UI screenshots. It does not use the required Problem, Change, Scope and approval, and Verification sections. It also omits the required issue or approval reference and focused test results.

Resolution

Rewrite the description using the required section headings. Add the applicable triaged issue or maintainer approval, explain why an exemption applies if relevant, and document focused tests or manual checks with observed results. State any checks that were not run.
