chore: release v5.0.0

[camcima]

Phase 1 of the release process (see RELEASING.md): version bump + CHANGELOG only. Nothing is tagged or published by this PR.

Version

5.0.0 was passed explicitly rather than letting release-it compute it. Two reasons:

1. No commit in v4.1.0..main carries a ! marker or BREAKING CHANGE: footer, so conventional-commits would have computed 4.2.0 — but this release is breaking (see below).
2. RELEASING.md advises passing the version explicitly regardless.

CHANGELOG was written by hand

The generated section had two defects, both corrected in this PR:

• No ⚠ BREAKING CHANGES section, for the reason above. Every prior major has one, and this release genuinely breaks custom persistence adapters.
• The whole release collapsed to a single line, because feat: definition version stamping (workflow versioning phase 1) #81 was squash-merged. RELEASING.md warns about exactly this: squashing collapses the individual feat:/fix: commits so conventional-changelog can no longer list them. Worth using a merge commit or rebase for content PRs next time.

The hand-written section documents the three breaking changes (required WorkflowInstance.definitionVersion; the Kysely WorkflowDatabase additions; the required 004 migration), the features, and two notes — that resolution is unchanged (the stamp is provenance, not pinning) and that correct multi-hop history ordering needs uuidStrategy: "uuidv7".

Verification

• pnpm run build — clean (ESM + CJS)
• pnpm test — 604 passed, 3 skipped (integration suites skip without DATABASE_URL)
• pnpm run test:coverage — 99.44 / 97.51 / 100 / 99.66, all four thresholds pass
• pnpm install --frozen-lockfile — succeeds, so Phase 2 won't trip on lockfile drift
• All packages at 5.0.0; @duraflows/core peer re-pinned to ^5.0.0 in pg, kysely, and nestjs

After merge

Phase 2 (tag, publish to npm, GitHub release) runs locally from main and needs GITHUB_TOKEN exported — .release-it.publish.json aborts without it.
