Summary

Adds the version-subscription drift detection and operator-apply workflow for per-workspace plugin tracking (core#113).

Components

Migration (20260510000000_plugin_drift_queue):

Adds installed_sha column to workspace_plugins — records the commit SHA installed so the drift sweeper can compare against upstream.
Creates plugin_update_queue table with status: pending | applied | dismissed.
Adds partial unique index to prevent duplicate pending rows per (workspace_id, plugin_name).

GithubResolver (github.go):

LastFetchSHA field + LastSHA() getter — populated by Fetch after a successful shallow clone (captured before .git is stripped). Used by the install pipeline to seed installed_sha.
ResolveRef(ctx, spec) method — resolves a plugin spec to its full commit SHA using git fetch --depth=1 + git rev-parse. Used by the drift sweeper to get the current upstream SHA for a tracked ref.

Drift sweeper (plugins/drift_sweeper.go):

Periodic sweep every 1h: SELECTs rows where tracked_ref != none AND installed_sha IS NOT NULL, resolves upstream SHA, queues drift if different.
ListPendingUpdates() — reads pending queue rows for the admin endpoint.
ApplyDriftUpdate() — marks entry applied (idempotent).
ctx.Err() guard on ticker arm to avoid post-shutdown work.

Install pipeline:

stageResult.InstalledSHA field carries SHA from Fetch to the DB.
recordWorkspacePluginInstall now accepts and stores installed_sha.
deleteWorkspacePluginRow — removes tracking row on uninstall so a stale SHA doesnt prevent the next install from creating a fresh row.

Admin endpoints (handlers/admin_plugin_drift.go):

GET /admin/plugin-updates-pending — list all pending drift entries.
POST /admin/plugin-updates/:id/apply — re-installs plugin from source_raw, records new SHA, marks entry applied, triggers workspace restart. Idempotent.

Router wiring (router.go, cmd/server/main.go):

Plugin registry created in main.go and shared between PluginsHandler and drift sweeper.
PluginsHandler.Sources() export for the sweeper wiring pattern.

Test plan

go test -race ./workspace-server/internal/plugins/...
go test -race ./workspace-server/internal/handlers/...
go build ./workspace-server/...
Integration test: install tracked plugin → simulate drift → verify queue entry appears → apply → verify SHA updated

## Summary

Adds the version-subscription drift detection and operator-apply workflow for
per-workspace plugin tracking (core#113).

## Components

**Migration** (`20260510000000_plugin_drift_queue`):
- Adds `installed_sha` column to `workspace_plugins` — records the commit SHA
  installed so the drift sweeper can compare against upstream.
- Creates `plugin_update_queue` table with status: pending | applied | dismissed.
- Adds partial unique index to prevent duplicate pending rows per
  (workspace_id, plugin_name).

**GithubResolver** (`github.go`):
- `LastFetchSHA` field + `LastSHA()` getter — populated by `Fetch` after a
  successful shallow clone (captured before `.git` is stripped). Used by the
  install pipeline to seed `installed_sha`.
- `ResolveRef(ctx, spec)` method — resolves a plugin spec to its full commit
  SHA using `git fetch --depth=1 + git rev-parse`. Used by the drift sweeper
  to get the current upstream SHA for a tracked ref (tag:vX.Y.Z, tag:latest,
  sha:…, or bare branch).

**Drift sweeper** (`plugins/drift_sweeper.go`):
- Periodic sweep every 1h: SELECTs rows where `tracked_ref != 'none' AND
  installed_sha IS NOT NULL`, resolves upstream SHA, queues drift if different.
- `ListPendingUpdates()` — reads pending queue rows for the admin endpoint.
- `ApplyDriftUpdate()` — marks entry applied (idempotent).
- ctx.Err() guard on ticker arm to avoid post-shutdown work.

**Install pipeline** (`plugins_install_pipeline.go`, `plugins_tracking.go`,
`plugins_install.go`):
- `stageResult.InstalledSHA` field — carries the SHA from Fetch to the DB.
- `recordWorkspacePluginInstall` now accepts and stores `installed_sha`.
- `deleteWorkspacePluginRow` — removes tracking row on uninstall so a stale
  SHA doesn't prevent the next install from creating a fresh row.
- Both Docker and EIC uninstall paths call `deleteWorkspacePluginRow`.

**Admin endpoints** (`handlers/admin_plugin_drift.go`):
- `GET /admin/plugin-updates-pending` — list all pending drift entries.
- `POST /admin/plugin-updates/:id/apply` — re-installs plugin from source_raw
  (re-fetching the same tracked ref), records the new SHA, marks entry applied,
  triggers workspace restart. Idempotent (already-applied returns 200).

**Router wiring** (`router.go`, `cmd/server/main.go`):
- Plugin registry created in main.go and shared between PluginsHandler and drift
  sweeper.
- `router.Setup` accepts optional `pluginResolver` param.
- `PluginsHandler.Sources()` export for the sweeper wiring pattern.

## Tests

- `plugins/github_test.go` — `ResolveRef` coverage (invalid spec, git error,
  not-found mapping, no-panic for all ref shapes).
- `plugins/drift_sweeper_test.go` — `ResolveRef` happy path, stub resolver
  interface compliance.
- `handlers/admin_plugin_drift_test.go` — ListPending (empty, non-empty, DB
  error), Apply (not found, already applied, already dismissed, workspace_plugins
  missing).

[core-lead-agent] LGTM. Closes #123 (plugin drift detector + queue + admin apply). 13 files, ~800 lines new code with 374 lines of tests (drift_sweeper_test.go + admin_plugin_drift_test.go). Migration adds installed_sha column + plugin_update_queue table with partial unique index. tier:medium → core-lead (managers) approval suffices.
