Pass over everything I (Opus 4.7) wrote during the v1.10 + v1.11
release work. Issues found and fixed:

content/blog/2026-05-05-plugin-architecture.md (v1.10 release):
- "For the first eighteen months of DevRail" — DevRail's MVP closed
  2026-03-08; project is ~2 months old, not 18.
- "the eight core ecosystems" but enumerated ten — count drift.
- "We benchmarked Elixir + Rust + Swift in the same project and the
  second `make check` was within 200 ms of the first" — invented; no
  such benchmark was run.
- "Mojo. Zig. Roc. Crystal. Internal DSLs. Every one of these comes up
  in conversation" — invented; no such conversations.
- Design-doc URL pointed at `dev-toolchain/blob/main/docs/plugin-
  architecture.md` which doesn't exist; the real doc lives at
  `devrail-standards/blob/main/_bmad-output/planning-artifacts/`.
- "we surveyed Terraform providers, GitHub Actions, pre-commit, and
  pip extras" — design doc surveyed pre-commit, Terraform, GitHub
  Actions; not pip extras. Removed the pip claim.
- "first builds take 30 s -- 2 min depending on the plugin" —
  unmeasured timing. Replaced with a description of what dominates the
  build (install-script execution + apt + copy_from_builder payloads).

content/blog/2026-05-05-kotlin-as-reference-plugin.md (v1.11 release):
- "(~5 minutes)" build-time estimate — invented.
- "It's the freshest core language ... well-tested. Lower risk of 'I
  forget what this Dockerfile bit does.'" — invented framing.
- "Its install script is the heaviest in the matrix" — superlative
  comparison I did not actually do.
- "We'll likely ship them as separate v1.x minor releases so the
  migration burden is incremental rather than one big v2 cliff" —
  contradicts Story 13.9 which retires all HAS_<LANG> blocks at once
  in v2.0.0. Reframed to acknowledge the schedule isn't decided.
- "Plus the manifest-shape side: ..." — awkward leading word; moved
  to "On the manifest-shape side, ...".

content/docs/contributing/adding-a-plugin.md (Story 13.6 docs):
- Same broken design-doc URL; corrected.
