**Title:** CLI exec command

**Status:** pending

**Dependencies:** 144

**Priority:** medium

**Description:** Add mcpctl exec --project NAME AGENT -- command for interactive session access

**Details:**

In src/cli/src/commands/ add exec.ts or extend existing:
1. Parse: mcpctl exec --project NAME AGENT -- command args
2. Find or create AgentSession for agent in project
3. If command provided: call POST /sessions/:id/exec, print output
4. If no command (or -- bash): attach via WebSocket to /sessions/:id/attach
5. Handle terminal resize (SIGWINCH), pass to WebSocket
6. Propagate exit code from session
7. Per design doc: exec drops human into working environment (cloned repos), NOT the agent's reasoning loop

**Test Strategy:**

Manual testing: mcpctl exec --project test myagent -- ls should list repo contents. mcpctl exec --project test myagent -- bash should give interactive shell.
