fix: propagate --cdp flag to daemon for reliable CDP reconnection (#857)

* fix: propagate --cdp flag to daemon via AGENT_BROWSER_CDP env var

The --cdp flag was not being passed to the daemon process as an environment
variable, causing auto-reconnection to fail. The daemon's auto_launch()
function checks for AGENT_BROWSER_CDP, but this was never set when spawning
the daemon.

This commit adds:
- cdp field to DaemonOptions struct
- AGENT_BROWSER_CDP env var setting in apply_daemon_env()
- flags.cdp propagation in main.rs

This ensures reliable CDP connection recovery when using --cdp with external
browsers like Lightpanda, Electron apps, or remote Chrome instances.

Fixes reconnection issues with --cdp flag after connection drops.

* chore: remove changeset
