chore(deps): bump unthrown to 5.0.0-beta.7

[btravers]

Bumps unthrown and @unthrown/vitest from 5.0.0-beta.6 to 5.0.0-beta.7, and raises the peer range on contract/client/worker to ^5.0.0-beta.7.

Which "latest"

latest on npm is still 4.3.0 — the stable v4 line. The v5 work ships under the beta tag, currently 5.0.0-beta.7. Since this package's 8.0 line already tracks v5 beta, taking latest would be a downgrade; this follows beta.

Both packages are listed in minimumReleaseAgeExclude, so the 7-day maturity gate does not apply.

What changed upstream

Neither change required code changes here.

returnType<R>() on the built-in matcher (minor). Pins a match's output type so every branch is checked against it, rather than the result being the union of branch returns. A drifting branch now fails on that branch instead of downstream. Reaches all five *ErrCases combinators, match's errCases handler, and standalone match(value).

result.mapErrCases((matcher) =>
  matcher.returnType<ApiError>().with(P._, (error) => new ApiError({ status: 500, error })),
);

tapErrCases no longer silently drops a defect(…) branch. Previously such a branch compiled but the value was discarded, so the pipeline carried on with the original Err — while a throw in the same position already produced a Defect. It now takes the throw route, producing a Defect whose cause is an AggregateError of [the branch's cause, the observed error].

Only breaking for code that relied on the drop. This repo has exactly one tapErrCases call site — packages/worker/src/activity-contract-errors.spec.ts:301 — and it logs rather than using the defect marker, so it is unaffected. The doc-comment example at packages/worker/src/activity.ts:297 is the same shape.

Verification

Check	Result
pnpm typecheck	12/12 tasks pass
pnpm test	pass — 105 contract tests, plus worker/client/testing
worker --project integration-inprocess	2/2 pass (real time-skipping server, ~7s)
pnpm lint	clean
pnpm knip	clean
pnpm --filter ./docs exec turbo build	clean

The in-process integration run matters more than the typecheck here: it exercises the actual runtime through the full contract pipeline against beta.7, which is where a matcher or defect-channel regression would show up. I did not run the Docker-backed integration project locally — CI covers it.

Also updated

• docs/how-to/install.md peer table and docs/how-to/upgrade-to-v8.md install command + checklist now say ^5.0.0-beta.7.
• Left upgrade-to-v8.md:38 ("built in again as of beta.6") alone — that is a historical statement about when the matcher stopped needing ts-pattern, and remains accurate.

returnType<R>() is not documented in our guides. It is unthrown's API rather than ours, but it would genuinely improve the mapErrCases examples where the output type is fixed by a signature — happy to add a short mention if you want it.
