* feat(plugins): add workspace panels and command center contributions
Give local plugins contextual UI entry points without making the daemon interpret client placement or callbacks. Panels receive stable IDs and read cached client state through required selectors with shallow equality, avoiding unrelated guest rerenders and context-discovery RPCs.
* fix(plugins): align shared client state ownership
Workspace panels and Command Center callbacks consume the same frozen client snapshots, so their adapter belongs to the plugin boundary rather than either contribution surface. Refresh the Nix dependency hash for the selector-store dependency added by this feature.
* fix(app): open notifications on the right host
Agent notifications previously omitted workspace ownership, so a cold target host was treated as missing and fell back to its empty home route. Carry the authoritative workspace and keep older notifications on a target-host resolver until lookup is conclusive.
* fix(app): separate notification and agent URL routing
Notifications use their authoritative workspace target directly. Stable agent URLs remain server-and-agent targets whose workspace is resolved by the agent route.
* fix(protocol): preserve notification workspace targets
Both attention message variants retain workspaceId through outbound validation so notification clicks receive the authoritative route target.
* test(app): use workspace-scoped notification target
* test(server): give notification agents workspace targets
* test(app): target notification workspace in navigation e2e
* fix(app): focus explicitly opened workspace tabs
Explicit tab navigation could be overwritten by attention-aware workspace
navigation when the visible agent had just finished. Make workspace navigation
own both normal attention selection and explicit targets so callers cannot
sequence them inconsistently.
* test(app): strengthen forked tab focus assertion
Nested native stacks fell back to the navigation library's light background during cross-stack swaps. Share the active app surface color across every stack without subscribing route layouts to all theme runtime changes.
* fix(app): keep composer autocomplete visible after route hops
Workspace callers now express only the target workspace. The navigation helper chooses whether to pop to a mounted host route or fall back, and active-workspace tracking ignores stale hidden route params while app-wide routes are foregrounded.
* test(app): address workspace navigation review
* fix(app): parse decoded legacy workspace routes
* fix(app): ignore decoded legacy tab routes
* test(app): use canonical offline workspace route
* fix(app): keep New Workspace on the active project
New Workspace preselection was falling back to stale remembered host state when multiple hosts existed. Pass durable active-project context from workspace entry points and centralize initial host selection so stale offline hosts cannot steal the form while startup restore remains last-workspace only.
* fix(app): address New Workspace review feedback
* fix(app): stabilize New Workspace host selection
* fix(app): preserve New Workspace host fallback
* test(app): loosen stale-host project assertion
* fix(app): prefer reachable new workspace hosts
* fix(app): avoid stale offline workspace preselect
* fix(app): prefer online project hosts
