cliffhall 58e53d5a92 fix: state every test-gate timeout instead of inheriting a library default
Three of the six Vitest projects ran on Vitest's own testTimeout: 5000 and
five on its hookTimeout/teardownTimeout: 10000, and all 788 Testing Library
waits in the web unit project ran on asyncUtilTimeout: 1000. None of those
numbers was chosen here, and all of them were sized for an idle machine rather
than for three or four concurrent worktree sessions each running a full
local:gate on eight cores. #2292, #2278, #2250, #1942 and #1742 were each that
class, diagnosed one site at a time.

This is the complement of #1596, not a retreat from it: every fix that issue
produced stands, and no race is hidden here. What changes is that a correct,
deterministic test is no longer cut off by a budget nobody picked.

- vitest.shared.mts exports frozen TIMEOUTS / INTEGRATION_TIMEOUTS; all six
  projects spread one of them, clients/launcher importing the shared module for
  the first time to do so.
- Both web projects configure Testing Library's asyncUtilTimeout. The storybook
  one needs its own setup file, deliberately outside .storybook/ and free of
  setProjectAnnotations so the automatic preview-annotation provisioning
  (#1898) is untouched.
- 28 per-suite restatements of the integration project's own budget are gone,
  so raising the shared value now moves every site under it. The handful that
  genuinely differ — cross-process lock contention, a full OAuth round trip —
  keep their budget as a named constant that says why.
- AppRenderer's waitFor no longer asks for exactly its enclosing budget, which
  it could never win (#2292's shape); cli's e2e child timer drops below the
  project budget so the bound carrying the diagnostic is the one that fires.
- The transition auto-settle's slack term is named RAF_SLACK_MS and raised;
  the term derived from HEADER_ANIM_MS is untouched. The two answer to
  different things and must not be scaled as one number.
- The 19 Playwright budgets scattered across three web smokes become four
  named constants in scripts/lib/browser-timeouts.mjs.

scripts/verify-test-timeouts.mjs resolves each project through Vitest itself
and asserts the budgets, the asyncUtilTimeout sites, and that retry stays
unset. It was observed red against the pre-change config: unit/tui/launcher at
testTimeout 5000, five projects at hookTimeout 10000, both asyncUtilTimeout
sites unmet.

Closes #2323
