A quick follow-up to 3.4.0 with a reworked task router, a live view into what the agent's doing, and a first-boot freeze fixed at the root.

• Task router redesign. Grouped lanes, icons, effective-model hints, and segmented concurrency controls; targets a single tab's session override when more than one tab is open; changing the topbar model now keeps the router's default slot in sync, and the model dropdown scrolls correctly inside the drawer.
• See what the agent's doing, live. A tasks panel above the composer streams the agent's task list as it updates; the goal reviewer's report text now reaches the desktop instead of being dropped; GoalBar gets a toggle for the reviewer's live steps and past verdicts.
• Maze choreography. Agent hops read as a fast swim instead of a teleport, dispatch and background workers hatch from and return to the organism instead of orbiting as static dots, the main agent perches while a swarm or the reviewer works nearby, and the camera eases in during review.

• A first-boot freeze. Migrating settings into place could hang the TUI on a fresh install when the filesystem couldn't clone files in place — regenerable data now skips cleanly instead of blocking, runtime files like a stale pid or lock never migrate, and a corrupt memory database is quarantined and recreated instead of bricking startup.
• The boot sequence stopped teleporting. Brand, picker, and version text now hand off on one shared clock instead of racing separate entrance animations; the workspace no longer replays its entrance after indexing; the logo no longer flashes when the halo settles.
• The genome popup showing 0 files after the map format overhaul — the parser now follows the directory-folded layout and groups files under their directory with a blast-radius heat bar.
• A loading state instead of a blank flash on the maze, browser, setup wizard, and full genome view while they lazily mount.
