Phase 2 of the parts-row autogen design — Crucible (sow-tools) side only.
Resolves parts 2DA rows from the immutable \`part.yml\` published with the asset HAK release, over the anonymous Bunny CDN channel, with the parts consumer **required** (no fail-open).
## Changes
- **Resolver (T3):** generalize \`resolveCDNChannelManifest\` — derive manifest basename + provenance label from config; drop hardcoded \`assets/vfxs.yml\` so \`part.yml\` resolves through the same path. VFX behavior unchanged.
- **Parts filter (T4):** \`filterCDNChannelEntries\` dispatches on consumer mode; new \`filterPartsCDNChannelEntries\` implements the inventory contract — \`restype: mdl\` under \`part/<supported-cat>/\`, row id from trailing digits, dedup l/r/race/gender variants by (category,rowID), sort by source, **zero accepted rows = hard fail**, reject row id 0 / non-numeric / malformed / no-assets.
- **Category (T5):** add \`hand\` + \`parts/hand\` mapping (12 datasets; \`leg→legs\` already present).
- **Pipeline (T6):** native build runs one explicit augment → normalize → override sequence under the configured \`parts_rows\` policy; overrides may update an existing/discovered row but **never synthesize** one (orphan override now errors).
- **Validation (T7):** reject more than one \`parts_rows\` consumer.
## Tests
9 new tests: parts filter contract, 12-dataset coverage, offline manifest-basename, orphan-override reject + discovered-row update, and a parity guard proving a bare CDN-only parts build needs no wrapper/token/NWN_ROOT/checkout.
Gate green: \`go test ./internal/topdata/... ./internal/project/...\` + full \`go build ./... && go test ./...\`.
## Scope / ordering
Phase 2 is inert until **Phase 1** (sow-assets-manifest publishes \`part.yml\`) ships and the operational **Gate** (release publish/promote) runs, then **Phase 3** enables the sow-topdata consumer. Do not enable the consumer against a channel whose current release predates \`part.yml\`.
