feat(plugins): secure installer — manifest, discovery, safe extract/fetch/scan (M4)
Plugins placed on the /plugins volume are now discovered, validated and registered
as inactive, ready to activate.
- manifest.ts: strict trek-plugin.json validation (id/version/type, known
permissions only, egress required with http:outbound, native modules rejected).
- discovery.ts: scans the volume on startup + on demand (POST /api/admin/plugins/
rescan), upserts rows INACTIVE, refreshes settings-field descriptors, and never
downgrades or wipes an already-installed plugin's status / grants / config.
Invalid or native-carrying plugins are skipped and logged.
- Activation now grants the DECLARED permissions (the consent gate) and persists
them before spawning.
- install/ utilities for the registry installer (M5), each independently tested:
- safe-fetch: host allowlist (GitHub only) + private-IP refusal + manual
redirect following + size cap + sha256 (constant-time compare).
- safe-extract: zip/tar-slip-safe extraction with its own minimal tar.gz + zip
readers; rejects traversal, absolute paths, symlinks, oversized/too-many
entries, and unsupported formats.
- native-scan: refuses .node / binding.gyp / prebuilds, never follows symlinks.
