RFC#2843 #42 — user-installed plugins wiped on restart

Flaw. A restart = a fresh ephemeral instance; the box's /configs/plugins is rebuilt entirely from MOLECULE_DECLARED_PLUGINS by the boot-install step. That env was stamped from the declared set only (workspace_declared_plugins). A plugin the user installed at runtime via install_plugin is recorded in workspace_plugins but never in the declared set — so it silently vanished on the next restart.

Fix. Stamp the union: desiredPluginSources() = declared (template intent) ∪ installed (workspace_plugins, the live runtime set), keyed by plugin_name.

• Declared seeds the first boot (before the post-online reconcile records workspace_plugins rows).
• Installed preserves user additions across restarts.
• On a name collision the installed source wins (reflects what's actually running, including a ref re-pinned via install_plugin).
• Empty-source_raw rows are skipped (nothing to fetch).

Only the small source list rides the env; the box fetches each source itself.

SOP

• Root cause: declared-only desired-set; restart rebuilds from scratch → additive user installs dropped. Same ephemeral-restart root as #32/#38.
• Five-axis: correctness (union covers first-boot + restart + collision), no-backwards-compat break (declared-only workspaces unchanged — union of declared+∅ = declared), security (no new secret surface; source list only), tests (4 unit cases below), observability (provision log unchanged path, non-fatal).
• Tests: TestDesiredPluginSources_{UnionPreservesUserInstalled,DeclaredOnlySeedsFirstBoot,InstalledSourceWinsOnCollision,SkipsEmptySource} + existing reconcile suite — all green locally (go build/go vet/go test ./internal/handlers).
• Memory consulted: ephemeral-restart = fresh instance (root of #32/#38); command-git to bypass token-stripping clone wrapper.

## RFC#2843 #42 — user-installed plugins wiped on restart **Flaw.** A restart = a fresh ephemeral instance; the box's `/configs/plugins` is rebuilt entirely from `MOLECULE_DECLARED_PLUGINS` by the boot-install step. That env was stamped from the **declared** set only (`workspace_declared_plugins`). A plugin the user installed at runtime via `install_plugin` is recorded in `workspace_plugins` but **never** in the declared set — so it silently vanished on the next restart. **Fix.** Stamp the **union**: `desiredPluginSources()` = declared (template intent) ∪ installed (`workspace_plugins`, the live runtime set), keyed by `plugin_name`. - Declared seeds the **first** boot (before the post-online reconcile records `workspace_plugins` rows). - Installed preserves **user additions** across restarts. - On a name collision the **installed** source wins (reflects what's actually running, including a ref re-pinned via `install_plugin`). - Empty-`source_raw` rows are skipped (nothing to fetch). Only the small source **list** rides the env; the box fetches each source itself. ### SOP - **Root cause**: declared-only desired-set; restart rebuilds from scratch → additive user installs dropped.

fix(provision): boot-install desired-set = declared ∪ installed (#42) ... 0db5b5cb43

A restart is a fresh ephemeral instance, so the box's /configs/plugins is
rebuilt entirely from MOLECULE_DECLARED_PLUGINS. That env was stamped from
the DECLARED set only (workspace_declared_plugins), so any plugin a user
installed at runtime via install_plugin — recorded in workspace_plugins,
never declared — silently vanished on the next restart.

Stamp the UNION instead (desiredPluginSources): declared (template intent)
∪ installed (live runtime set, workspace_plugins), keyed by plugin_name.
Declared seeds first boot before the post-online reconcile records rows;
installed preserves user additions across restarts. On a name collision the
installed source wins (it reflects what is actually running, including a ref
the user re-pinned). Empty-source rows are skipped.

Adds listInstalledPlugins (name+source_raw) and desiredPluginSources, with
unit coverage for: user-installed survives, declared-only seeds first boot,
installed-source-wins-on-collision, empty-source skipped.
