* perf(app): reduce warm workspace switch work
Retained workspaces avoided mounts but pane activity still rerendered the full composer, message input, and agent-control presentation. Keep the activity contract intact while moving focus-sensitive behavior behind small context consumers, and add a Playwright benchmark that measures rapid retained workspace switching on one browser clock.
* perf(app): accelerate retained workspace switching
Avoid repeated retained-stream layout reconciliation and unrelated workspace structure recomputation. Use the lightweight route transition while the host is already focused, while preserving targeted root POP_TO for returns from app-wide routes where it prevents duplicate hidden decks.
* perf(app): defer composer focus during workspace switches
* perf(app): retain recently used workspaces longer
Keep up to ten workspace screens warm so normal multi-workspace navigation does not repeatedly rebuild recently used timelines. Inactive screens expire after ten minutes, while the active screen remains protected and capacity eviction stays least-recently-used.
* fix(app): reconcile retained timeline geometry
* fix(app): refresh retained reading position
* fix(app): move keyboard focus to target pane on keyboard navigation (#137)
Add a pane focus registry so each panel type can expose its own focus
callback. When keyboard shortcuts navigate between panes, the workspace
screen calls the target panel's registered focus function, moving DOM
focus to the correct input element.
- Agent panels register a callback that focuses the message input
- Terminal panels register a callback that triggers terminal focus
- Panel-internal focus logic stays inside each panel type
- No DOM selectors or panel knowledge in shared infrastructure
* fix(app): simplify workspace pane focus handoff
