chore(deps): bump unthrown to 5.0.0

[btravers]

Summary

unthrown 5.0.0 is out of beta. Catalog and peer ranges move from 5.0.0-beta.7 to the stable release.

The only API change between beta.7 and 5.0.0 is that the standalone tag export moved onto the pattern namespace as P.tag(t) (unthrown beta.9), joining every other pattern constructor. The type and runtime behaviour are unchanged, so the migration is purely a rename.

Changes

• Catalog: unthrown and @unthrown/vitest → 5.0.0
• Peer range on contract / worker / client → ^5.0.0
• tag(...) → P.tag(...) across source, tests, TSDoc examples, READMEs and the docs site; tag dropped from every unthrown import in favour of P
• docs/how-to/install.md: peer table shows ^5.0.0
• docs/how-to/upgrade-to-v8.md: unthrown@beta → unthrown@^5 (unthrown itself is stable now — only the @temporal-contract/* packages are on the beta tag), plus a tag → P.tag note and checklist item for anyone already tracking an 8.0 beta
• Changeset: patch on contract / worker / client (the 8.0 major is already carried by existing changesets)

Verification

pnpm install, pnpm lint, pnpm typecheck, pnpm test, pnpm knip, pnpm build and pnpm format all clean. Typedoc API docs regenerated (gitignored, so not in the diff).

• This example uses P.tag(...) but doesn’t define or import P. Adding import { P } from "unthrown"; makes the snippet self-contained.
