feat: backspace/space/erase editing commands + colored prefixed console

voice editing: 'space [<n>]' inserts spaces, 'backspace [<n>]' (alias delete)
deletes chars, 'erase' (alias clear/wipe) wipes the current input. the daemon
tracks a per-session uncommitted-input char count so backspace is capped at the
last submit boundary and erase clears exactly back to it; submit/set reset it.
keys.py gains BSpace/space; grammar gains a count parser (digits + number words).

new console.py renders every daemon line as 'HH:MM:SS [prefix] message' with
color: [<session>] for injected lines (green), [SYSTEM] for state, [VOICE] for
recognition/drops (red/dim). bump to 0.1.2.

-**cc kit** writes this file when you attach, so the target is "the project you most
-recently attached to". `claudedo switch <name>` / `target <name>` overwrites it. If

+A `target <name>` voice command is a **one-shot** that does NOT touch the sticky

+Resolution order (one place — `target.resolve()`): one-shot if present →
