PluginManagerScreen

Compose the manager screen.

Apply initial render, then load plugin state off the UI thread.

Stop accepting deferred refreshes once the screen is torn down.

Refit width-sized dividers when the modal resizes.

Update the live MCP connection snapshot and re-render.

The constructor only receives a snapshot of the app's connection state, so a manager opened while a connection is still settling would otherwise keep mcp_connecting=True forever — suppressing, for session-loaded plugins that declare MCP servers, both the "connected" indicator and a legitimate "run /reload" hint until the modal is closed and reopened. The app calls this whenever a connection attempt settles — ServerReady or a startup failure, including reconnects — so the open manager reflects the final connection state.

Gate priority bindings that would otherwise steal Input keystrokes.

/ is enabled only when the plugin filter is visible and not focused, so it remains typeable in the filter and Add Marketplace source field, and cannot steal focus while the filter is hidden. Left/right release to a focused Input once it has at least one character, so caret movement works while empty-field arrows keep switching tabs.

Focus plugin search when a letter is typed from another control.

Seed the character into the filter before focusing so the input never paints empty with a caret flash (and so select_on_focus cannot leave the inserted text selected for the next keypress).

Switch tabs from a mouse click on a tab label.

Apply pending plugin changes from the inline reload prompt.

Clear a query, back out of a view, answer the reload prompt, or close.

Answering the reload prompt dismisses the manager with "later"; the final branch only starts the close check, so the screen may stay mounted afterwards.

Focus the plugin filter when it is visible.

Switch tabs via right arrow when the caret is not editing text.

Switch tabs via left arrow when the caret is not editing text.

Switch tabs or focus the next details option.

Switch tabs or focus the previous details option.

Move the option-list cursor down.

Move the option-list cursor up.

Handle row activation.

Filter the current plugin list as the search query changes.

Activate a search result or start adding a marketplace.
