Pushed a Fern audit/fix pass in 4bd20f6a1d.

What changed:

• Fixed dead/stale anchors across release artifacts, nightly info, observability, routing, vLLM/TRT-LLM, AIConfigurator, agents, multimodal, and release-note pages.
• Tightened redirects for the Use Cases reorg, RL continuity URLs, DynoSim renamed routes, component reference pages, and model deployment intro URLs.
• Fixed the stale overview/:slug* redirect behavior that could hijack canonical overview pages; validated the prior problematic agents/overview/session-i-ds style URLs.
• Filled the Kubernetes model storage overview stub and cleaned up a few nav/title mismatches.

Local validation:

• npx --yes fern-api@5.80.2 docs broken-links passes.
• npx --yes fern-api@5.80.2 check --warnings has 0 errors; only existing warnings are unauthenticated missing-redirect audit and light-mode accent contrast.
• git diff --check passes.
• Targeted local smoke tests for canonical pages and reorg redirects returned 200s.

CI diagnosis — two independent failures:

1. operator (make check) fails on a dirty tree, caused by this PR: docs/fern/pages/reference/kubernetes-api/additional-resources/api-reference-k8s.md is generated by make -C deploy/operator generate-api-docs, so the two hand-edits stripping the #endpointpickerconfig anchor get regenerated. Revert them, or fix the anchor at the source (deploy/operator/docs/crd-ref-docs-config.yaml / docs/fix-api-anchors.py) and commit the regenerated file.

2. Operator Integration golden mismatch is not from this PR — it is branch staleness: this branch is 48 commits behind main, with a merge base predating fix(profiler): configure rapid mocker without planner #12573, which made --planner-profile-data conditional and regenerated deploy/operator/internal/controller/testdata/dgdr/*/output.yaml. Merging main should clear it.
