librelad caee74bd76 feat(distribution): signed artifact-index fetch+verify primitive (Phase 1)
Build the read side of the unified distribution primitive from
docs/roadmap/updates-and-distribution.md: one team-signed catalog
(index.json) on the same channel as latest.json, listing type-tagged
artifact envelopes. A hotfix is the first artifact type; apps/themes/
components are future envelope rows through the SAME pipe — the
marketplace seam is just the `type` + `payload.kind` fields.

Phase 1 is fetch + verify + parse only (NO mutation; the snapshot →
ops → rollback → History apply verb is Phase 2):

- Factor `lpVerifyMinisig` out of `lpFetchRelease` (scripts/source/
  fetch.sh) — one trust anchor (the root-owned footprint key) now
  shared by releases and the index; refactor `lpFetchRelease` to use
  it (behaviour-preserving, still fail-closed).
- scripts/source/artifacts.sh: `lpFetchIndex` — download →
  verify-before-parse → `valid_until` freshness (anti-withholding) →
  `index_serial` monotonic high-water (anti-rollback, TUF-lite) → emit
  verified JSON. Trust core is jq-free; parsing accessors prefer jq
  with a grep fallback.
- `libreportal artifact index` (scripts/cli/commands/artifact/) —
  read-only front door that fetches, verifies and lists. Runs directly
  like `updater check` (no task; no mutation).
- Regenerate the source arrays + lazy-load function manifest for the
  new files.

Doc: promote the format from vision to spec (§8) — 3 layers
(INDEX/ENVELOPE/PIPELINE), the bounded declarative op vocabulary (no
run-script, ever), the apply pipeline mapped onto existing functions,
the marketplace seam, and resolutions for all five open forks.

Self-tested 12/12: trust core fails closed (real key + no minisign →
refuse), happy path, stale-refused, rollback-refused, signature-refused,
jq + grep parsing.
