Adds make fast: lint, typecheck, then scripts/check-affected.ts --base origin/main. It is the quickest local read on the first red CI step. make check stays the gate and does not call fast.

scripts/fast.test.ts asserts fast is in .PHONY, that its recipe is those three lines, and that the check recipe does not mention fast. With fast removed from the Makefile, the first two assertions fail.

The levels (verification) check fails in tests/structure/lab-solutions.test.ts for advanced-05 items 2 and 4. This PR does not cause it.

The lab's solution script runs grep -qF 'Bash(git push *)' against .claude/settings.json. Commit caba5f9 on main replaced that deny entry with narrower ones, so the grep now fails. This PR touches only Makefile and scripts/fast.test.ts.

No fix exists yet. The fix is in labs/advanced/05-cloud-session-guardrails.md and its expected output, which is outside this PR's scope, so I have not widened it. The review check also failed once when the Claude Code Action exited with no output. I re-ran that job once.

The trunk check fails because of this PR. tests/structure/levels.test.ts reports scripts/fast.test.ts: no owner, since levels.json has no entry for the new test file.

The fix is one line in levels.json, next to scripts/check-affected.ts and scripts/impact.test.ts in the level that owns them. The task that produced this PR forbade editing levels.json, so I have not pushed it. It needs your call on which level should own the file.

The other red checks (levels (*)) fail on the lab advanced-05 problem from main, covered in my earlier comment. The review job failed again on its re-run, so the Claude Code Action looks broken independent of this PR.
