feat(coder): unified Plan/Ask/Bypass permission picker

Replace the raw per-agent mode dropdown in the BooCoder composer with a
curated three-option permission ladder mapped generically onto each
provider's native modes: `plan` id -> Plan, default -> Ask, isUnattended
-> Bypass (claude bypassPermissions, qwen yolo, opencode full-access).
modeId stays the single wire field; the active unified mode is derived
from it (no contracts change).

Native BooCode gains its own mode set: Ask stages to the pending-changes
queue (today's behavior), Bypass auto-applies the queue to disk after the
turn (interactive messages path + task dispatcher path), Plan falls back
to Ask. The shared apps/server inference engine is left untouched.

Also preserve isUnattended on live-probed ACP modes so opencode's bypass
mode stays detectable from the wire.

Coder 373 tests green; coder + web typecheck clean.
