/drop works like /new but permanently deletes the current session file
and artifacts instead of flushing (saving) it. Useful when the session
should not be kept.
- add drop?: boolean to NewSessionOptions
- branch in AgentSession.newSession(): skip flush, delete via
FileSessionStorage.deleteSessionWithArtifacts when drop=true;
deletion failure is non-fatal (logged, new session still starts)
- wire handleDropCommand() through InteractiveModeContext interface,
InteractiveMode delegation, and CommandController implementation
- guard: shows error if session has not been saved yet (no file to drop)
- register /drop in builtin-registry adjacent to /new
