v0.6.0

Phase 7b — live worker visibility

A dispatch_chakla worker batch is now observable in real time (previously: one spinner, then a single block when all workers finished).

• Live "flock" table (TUI): one row per worker — queued → running → done/timeout/error — with the worker's current activity (per-tool-call detail, e.g. "running nmap…") and a live token count. The table is ephemeral: removed when the dispatch finishes; the aggregated text summary remains.
• Worker token/cost in the status bar: the 🐦 segment now populates as each worker completes (tracked separately from the main gauge, no double-counting; resets with /clear and /new).
• Headless progress: one stderr line per finished worker (🐦 [i] task — done (…)); stdout stays the agent's answer stream.

Under the hood: a small, optional, UI-agnostic tool→UI progress channel (a progress callback on ToolContext). The 7a worker gating/safety contract is unchanged.
