2df4e28a85 feat(distribution): Phase 2 — artifact apply/revert pipeline + ops interpreter
The mutating side of the unified distribution primitive (spec §8.3). Hotfixes
can now be applied and reverted, first-party, through the task system.

New scripts/cli/commands/artifact/cli_artifact_apply.sh:
- artifactApply <id>: resolve+gate (applies_when / min_lp / max_lp /
  max_footprint / publishers-map role) → fetch+verify payload (sha256 pinned by
  the signed index + minisig) → dry-precheck ALL ops (all-or-nothing) → best-
  effort snapshot → apply each op recording a precise inverse → bring app up →
  auto-rollback (replay undo LIFO, snapshot fallback) → applied-record + History.
- artifactRevert <id>: replay the applied-record's undo log (LIFO).
- Bounded, CLOSED op vocabulary (no run-script/exec, ever): set-config-key,
  set-compose-image, patch-file-if-checksum-matches, set-data-file. An
  unsupported op rejects the whole artifact at precheck (fail-closed).
- Write-target firewall: scope:app → containers/<app>/ only; scope:system →
  configs/ only; the install tree (our code) is off-limits to hotfixes (fork 1).
  Drift guards (expect_current / checksum) skip cleanly rather than clobber.
- Two-tier trust: index minisig-verified vs the footprint key (lpFetchIndex)
  covers the envelope; payload sha256-pinned + minisig-verified; publishers-map
  role gate (a non-official publisher can't claim official). Community per-
  artifact-key sigs are gated off until that tier is enabled.

cli_artifact_commands.sh: apply/revert via the task system (artifact_apply /
artifact_revert types — no allowlist needed), + read-only `applied` list.

cli_updater_commands.sh:
- FIX verified safety bug: updaterApplyApp/RollbackApp called `libreportal backup
  app "$app"` and `... restore latest`, which parse the app name as the ACTION,
  hit the dispatcher's `*)` default (exits 0) — so updates ran with NO snapshot
  and rollback was a silent no-op. Call backupAppStart / restoreAppStart directly.
- FIX updaterRecordHistory jq-silent-skip: was `command -v jq || return 0`
  (silently dropped the audit entry). Now fail-closed with a brace-agnostic
  bash-native prepend fallback; extended with artifact_id/serial/undo_id.

fetch.sh: add _lpJsonEsc (shared JSON-escape for the jq-free fallbacks).
Regenerated source arrays + lazy-load manifest for the new file/functions.

Unit-tested 31/31: every op apply+precheck+undo round-trip, the path-allowlist
firewall (incl. .. traversal + install-tree + cross-app rejection), all-or-
nothing abort, unsupported-op rejection, and the History bash-native fallback
(records + preserves prior entries without jq). A full signed-apply e2e needs
minisign + the signing key (Phase 5 make_hotfix.sh).

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.
