Split session management (9P and D-Bus) out of the monolithic system
prompts into dedicated files primed separately:
- session-9p.md: 9P filesystem session operations
- session-dbus.md: D-Bus method/signal session operations
System prompts are now server-agnostic. The install target copies
the appropriate session-*.md as session.md. Agent configs prime
"session" after "SYSTEM_PROMPT" to compose the full prompt.
This eliminates the N×2 variant matrix (one -9p and -dbus per model)
and makes adding new model prompts simpler.
- agent JSONs: $OLLIE/x/ -> $OLLIE_CFG_PATH/scripts/x/
- x/prime: use $OLLIE_PROMPTS_PATH instead of $OLLIE/p/
- x/elevate-adapter-start: use $OLLIE_CFG_PATH/scripts/x/
- Update core and 9p submodules
olliesrv and agent sessions now work without FUSE. Mount remains
available as an enhancement when present.
