app-server: allow remote_control runtime feature override (#20047)

codex-rs/app-server/README.md

@@ -192,7 +192,7 @@ Example with notification opt-out:
 - `fs/changed` — notification emitted when watched paths change, including the `watchId` and `changedPaths`.
 - `model/list` — list available models (set `includeHidden: true` to include entries with `hidden: true`), with reasoning effort options, `additionalSpeedTiers`, optional legacy `upgrade` model ids, optional `upgradeInfo` metadata (`model`, `upgradeCopy`, `modelLink`, `migrationMarkdown`), and optional `availabilityNux` metadata.
 - `experimentalFeature/list` — list feature flags with stage metadata (`beta`, `underDevelopment`, `stable`, etc.), enabled/default-enabled state, and cursor pagination. For non-beta flags, `displayName`/`description`/`announcement` are `null`.
-- `experimentalFeature/enablement/set` — patch the in-memory process-wide runtime feature enablement for the currently supported feature keys (`apps`, `plugins`). For each feature, precedence is: cloud requirements > --enable <feature_name> > config.toml > experimentalFeature/enablement/set (new) > code default.
+- `experimentalFeature/enablement/set` — patch the in-memory process-wide runtime feature enablement for the currently supported feature keys (`apps`, `memories`, `plugins`, `remote_control`, `tool_search`, `tool_suggest`, `tool_call_mcp_elicitation`). For each feature, precedence is: cloud requirements > --enable <feature_name> > config.toml > experimentalFeature/enablement/set (new) > code default.
 - `collaborationMode/list` — list available collaboration mode presets (experimental, no pagination). This response omits built-in developer instructions; clients should either pass `settings.developer_instructions: null` when setting a mode to use Codex's built-in instructions, or provide their own instructions explicitly.
 - `skills/list` — list skills for one or more `cwd` values (optional `forceReload`).
 - `marketplace/add` — add a remote plugin marketplace from an HTTP(S) Git URL, SSH Git URL, or GitHub `owner/repo` shorthand, then persist it into the user marketplace config. Returns the installed root path plus whether the marketplace was already present.
