Conversation
Enable agents to hot-swap their conversation context to a persisted session at runtime, following the same ControlCommand pattern as Clear/Rewind/ModelSwitch. Architecture: - ControlCommand::ResumeSession + AgentEventPayload::SessionResumed in protocol layer - AgentLoopRunner::handle_resume_session replaces session identity, context store, and resets counters (runtime layer) - SessionController::resume_session clears display + sends command (session layer) - TUI receives SessionResumed event → loads display history including sub-agents CLI: - `--resume` (no ID) auto-finds latest session for current directory - `--resume <ID>` resumes specific session (backward compatible) - ResumeIntent enum encapsulates the clap sentinel, resume field is private TUI: - `/resume` lists recent sessions for current project - `/resume <prefix>` hot-swaps agent context (prefix match on session ID) - `/sessions` removed (subsumed by /resume) Storage: cwd canonicalized via normalize_cwd for reliable path matching.

Summary
ControlCommand::ResumeSessionso agents can hot-swap their conversation context to any persisted session at runtime, following the same pattern as Clear/Rewind/ModelSwitch--resumeCLI flag now works without an ID (auto-finds latest session for current directory); typed viaResumeIntentenum instead of rawOption<String>/resume <prefix>triggers real agent-level context swap;/resume(no arg) lists recent sessions;/sessionsremoved as redundantChanges
