* fix(core): make deploymentId 'latest' a no-op in non-Vercel worlds
Previously, start({ deploymentId: 'latest' }) threw a WorkflowRuntimeError
in any World that doesn't implement resolveLatestDeploymentId() (local dev,
Postgres). That meant a workflow which opts into 'latest' on Vercel would
fail outright in local development.
Resolving 'latest' only means something in worlds with atomic, immutable
deployments. In other worlds there is nothing to resolve between, so instead
of throwing we now log a warning and fall back to the current deployment,
making 'latest' an effective no-op there.
- start.ts: warn + fall back to currentDeploymentId instead of throwing
- start.test.ts: replace the "should throw" test with a warn + fallback test
- e2e.test.ts: assert 'latest' completes (no-op) on non-Vercel worlds
- docs: note the no-op behavior in v4 + v5 start.mdx

* fix(core): warn once for deploymentId 'latest' no-op; harden test cleanup
Address PR review:
- Gate the 'latest'-has-no-effect warning behind a once-per-process guard
(mirrors the warnOnce pattern in constants.ts) so a workflow that hardcodes
'latest' for Vercel doesn't flood local/Postgres dev logs on every run.
Exposes _resetLatestNoOpWarnForTests() (@internal) for unit tests.
- start.test.ts: reset the guard in beforeEach and restore spies in afterEach
via vi.restoreAllMocks() so a throwing assertion can't leak the
runtimeLogger.warn spy into later tests; drop the manual mockRestore().
- Add a test asserting the warning fires exactly once across repeated
'latest' starts while every run still falls back to the current deployment.
