Toolsets that exist only for one kind of session now say so on their spec:
`platforms=frozenset({"desktop"})`. `TOOLSET_SESSION_PLATFORMS` is derived
from the specs that carry the key, `all` / `*` / no selection skip those
toolsets, and `toolsets.agent_tool_drops(agent)` removes their tools from any
agent whose own session platform is not listed. `agent_init._load_tools` and
`tools/mcp_tool_agent.py` (MCP refresh and prefix restore) call that one
helper. `tool_search._DIRECT_SURFACE_TOOLSETS` is derived from
`CLIENT_SURFACE_TOOLSETS` and `TOOLSET_SESSION_PLATFORMS`.
This replaces the profile-role gate: `profile_role_toolsets`, the role code in
`_with_session_toolsets` and the explicit-pin branch, the strip step in
`_select_tool_names`, and main's `setup` toolset (whose only tool moves out)
are deleted. `manage_catalog` moves into a new `catalog` toolset, which the
desktop client folds into every desktop chat like `project` and `desktop_ui`.
It is deferred behind tool_search by default (`config_defaults` defer list).
The shared-metrics schemas' toolset enum follows (`setup` out, `catalog` in).
The install card works outside the setup chat (#129650, with review fixes):
- Parallel installs: `_set_plugin_enabled` holds a per-home lock around the
read-then-admit section, so rows enabled at once no longer refuse each other.
- A catalog plugin already on disk and not enabled is enabled in place, so Try
again after a refused enable can finish.
- A failed catalog row counts as resolved (`contract.resolves`), so it no longer
holds the turn to the 300 s deadline. The snapshot carries `resolved`, and the
card reads it instead of a hand copy of the backend's rule.
- Each card draws its own operation by op id, because models reuse call ids.
- The row carries the approved non-secret choices (`approved`: force, enable,
ref) and the chosen profile, so Try again after the card settled repeats them.
- Install phases are ids (`InstallPhase`, wire `CatalogInstallPhase`) and the
installed-row notes are fields (`enabled`, `missing_env`, `server_errors`,
`already_installed`, `requires_hermes`); the card words them in English
strings (translations follow later). Failure reasons stay raw text, and
`detail` keeps the English notes for the model.
- Installs and search target the calling chat's own home, carried as a path;
the row's profile name is only a label, with no `'default'` fallback in
Python or TypeScript.
- `dashboard_install_plugin` is split into `_resolve_source`, `_place_tree` and
`_enable_placed`.
Desktop English strings for the card move to `en_catalog_install.ts` /
`types_catalog_install.ts`, which offsets the growth of `en.ts` and `types.ts`.
