add per-session status strip: model / permission-mode / context (T-145)

The transcript reader now also extracts a SessionStatus — current model
(assistant message.model), permission mode (the permission-mode records,
previously skipped), and context-window tokens (message.usage input +
cache-read + cache-creation) — and emits it on a statusStream, merging
deltas so it only fires on change. All CC-internals parsing stays in the
drift-contained reader (D-75).

The Claude pane renders this as a thin strip above the conversation
(model · permission-mode · context). Context is shown as a token count,
not a percentage: the transcript carries usage but not the model's window
limit, and the model id doesn't encode the 1M vs 200k tier.

Lead pane done; teammate-tile mirror and the sidebar (T-141) consume the
same status next.
