feat(cli): Create CLI manager with process lifecycle and output buffering

[coderooz]

Summary

Create the core CLI command execution manager with process lifecycle management, output buffering, and blocked command safety.

Acceptance Criteria

• Create \src/domains/cli/cli-manager.js\ with \CLIManager\ class
• Process registry: Map of processId → ProcessInfo
• Async command execution via \child_process.spawn\
• Output buffering (stdout/stderr) capped at 1MB per process
• Background mode: return immediately, poll output later
• Foreground mode: wait up to timeout (default 30s)
• Process signals: SIGTERM, SIGKILL for cleanup
• Zombie process detection (no output for 60s = failed)
• Max concurrent processes: configurable (default 10)
• Blocked command patterns (security):
  • 
    m -rf /,
    m -rf ~, \ormat, \del /s /q\
  • \shutdown,
    eboot, \halt\
  • Destructive pipe patterns
• Command confirmation: dangerous commands return { requiresConfirmation: true }\

Class Interface

\\js
class CLIManager {
constructor(config = {}) {}
async runCommand({ command, args, cwd, timeout, background, agent }) {}
getOutput(processId, offset) {}
listProcesses(statusFilter) {}
async killProcess(processId, signal) {}
async cleanup() {}
isCommandBlocked(command, args) {}
}
