plan(v0.22): release-planning slices as requirements (release: v0.22.0)

[avrabe]

Makes the v0.22 plan live in the trace (not a spreadsheet) by filing the four scoped slices as proposed requirements, each tagged release: v0.22.0. Queryable today:

$ rivet list --filter '(= release "v0.22.0")'
REQ-232  rivet list --release <ver> filter sugar           (#516 §2)
REQ-233  rivet release status <ver> readiness burn-down    (#516 §3, centerpiece)
REQ-234  rivet release move <id> <ver> logged scope change (#516 §3)
REQ-235  rivet migrate --explode <source> to per-id files  (#490 §2, DD-070)

v0.22 theme: complete release-planning — finish what v0.21 started (the release: field is half-useful without a burn-down query). Each slice is small; the field + loader already exist.

Dogfood notes (both are wins of the methodology):

• Filing these with --set-release exercised and confirmed the v0.21.1 corruption fix — all four carry provenance: blocks and validate cleanly.
• Found a minor routing quirk: rivet add --type requirement appended REQ-233 to cross-git-investigation.yaml (another file holding a requirement-type artifact) rather than requirements.yaml — find_file_for_type is order-dependent. Functionally fine (the trace is file-agnostic), but worth a follow-up; Design: shard artifacts/requirements.yaml into per-id files so parallel adds never share a region (structural fix for #422) #490's per-id layout sidesteps it entirely.

Once merged, v0.22 implementation starts at REQ-232 (list --release). validate PASS; docs check PASS.
