feat(native-chat): read ZCode session transcripts through the OpenCode SQLite reader

Browse Source 
ZCode's CLI persists an OpenCode-v1-shaped history in its own SQLite store
(~/.zcode/cli/db/db.sqlite). The Agent Session History scan already lists
those sessions, but opening one in the native chat found nothing: the chat
transcript path had no ZCode awareness.

Resolve a zcode transcript against the ZCode database (native home, then WSL
homes) before any OpenCode install, tag every read (signal, page, subscribe)
with the agent, and apply the same hidden-transcript filter the scan uses so
ZCode's hidden bookkeeping rows stay out of chat renders.
