Execution is now identical for local and remote:
- Session calls Spawn()/SpawnRemote() → owns *Process with socket
- Clients call Dial(LocalAddr(socket)) → *Conn over Unix socket
- ollie-remote serves --listen mode with multi-client accept loop
- Builtins (shell, tool_load, skill_load) run in subprocess with registries
Lifecycle:
- Pdeathsig ensures children die with parent (no orphans)
- Cleanup: SIGTERM → 3s grace → SIGKILL (guaranteed)
- Socket paths use atomic counter for uniqueness
- Session Kill() closes Process
Protocol:
- Extended RPC: set_env, set_cwd, detach, list_detached, etc.
- Shell goes through builtin dispatch (parses 'cmd' field correctly)
- Streaming output via JSON-RPC notifications
- Skip cwd existence check when remote is specified (cwd is on remote)
- Add BatchMode=yes to SSH: pubkey-only, no password fallback
- Add StrictHostKeyChecking=accept-new: auto-accept new hosts, reject
changed keys
- Deploy failure already propagates as session creation error via
RemoteDial returning error
When a session is created with a cwd that doesn't exist, all tool
execution fails with a confusing 'fork/exec landrun: no such file or
directory' because exec.Command sets cmd.Dir to the non-existent path.
Validate that cwd exists and is a directory at session creation time,
returning a clear error instead of allowing a broken session.
Also includes the earlier USER/NAMESPACE env export fix (agent.go,
shell.go) for the ollie-9p namespace path issue.
