feat(sdkclient): complete Client with dial, translate, and provider mapping (PR1 S3) - #91

Conversation
…apping (PR1 S3) Third slice of the PR1 SDK-foundation ladder (S1 #89, S2 #90). Completes the working openshell.Client over the OpenShell SDK, behind the harness firewall. - dial(connPlan) executes every auth branch: mTLS (verified live), default, and SA-OIDC (dialSAOIDC; compiled and branch-selected but // UNVERIFIED — no OIDC gateway available; gates PR8). - errors.go: translate() is the single owner of SDK-error meaning, mapping v1.Is* typed errors to the openshell.Err* sentinels; unknown errors pass through unchanged. Callers branch via errors.Is, never on SDK codes. - provider.go: fromSDKProvider maps the SDK provider view to the minimal harness Provider (least-exposure firewall). - NewFromClient is the injection seam (used by white-box tests and S4 testutil); New now routes through the general dial(plan) path. - Health() and Providers() are live and route errors through translate(). - connPlan gains non-secret oidcIssuer/oidcClientID for the SA-OIDC dial; the client secret is still never stored in the plan (re-read at dial time only). White-box tests via the SDK fake cover Health (healthy/unhealthy), Providers (with/without), translate (all SDK codes + nil + passthrough), error translation on a closed client, and Close idempotency. Firewall unchanged: internal/openshell/sdkclient remains the only production package importing the SDK; internal/openshell has zero SDK imports. Additive only.

WalkthroughThe SDK client now executes configured connection plans, supports mTLS, default, and service-account OIDC dialing, bounds OIDC grants, translates SDK errors, lists mapped providers, and applies workspace defaults. Tests cover health, providers, errors, and repeated close calls. ChangesSDK client support
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The service-account OIDC path caches and forwards access tokens instead of using the required credential-resolution approach, creating a concrete credential-handling risk if that branch is used.

Addresses CodeRabbit review on PR #91. oidc.ClientCredentials returns a one-shot token that expires, and v1.RefreshableToken re-calls its source once the cached token nears expiry — so oauth2.StaticTokenSource pinned a single token and would break auth the moment it expired. Replace it with an eager grant (preserving fast-fail ErrUnauthenticated classification) wrapped in oauth2.ReuseTokenSource(tok, refresher), where the refresher re-runs the client-credentials grant on a context.WithoutCancel context so refreshes outlive the dial call while keeping context values. The eager token is served first (no wasted grant). Secret is read fresh from the environment inside the source at grant time and never stored on the plan. Path remains // UNVERIFIED (no OIDC gateway); gates PR8.

- Around line 141-144: Bound each OAuth refresh grant in the ReuseTokenSource
setup by creating a client-owned context with a finite timeout for the
clientCredentials call, and cancel that context after the grant completes.
Update the refreshCtx/tokenSourceFunc flow while preserving token reuse and the
existing clientCredentials invocation.

Addresses follow-up CodeRabbit review on PR #91. context.WithoutCancel strips the parent deadline as well as cancellation, so a stalled OIDC token endpoint could block a background token refresh indefinitely. Bound both the eager grant and every refresh grant with their own context.WithTimeout(oidcGrantTimeout=30s), cancelled after the grant. Token reuse and the existing clientCredentials invocation are preserved. Path remains // UNVERIFIED (no OIDC gateway); gates PR8.
