New Features

• Chrome profile login state reuse - --profile <name> now resolves Chrome profile names (e.g. Default, Profile 1) and copies the profile to a temp directory to reuse login state, cookies, and extensions without modifying the original. Added profiles command to list available Chrome profiles with --json support (#1131)

Bug Fixes

• Fixed --ignore-https-errors not passing --ignore-certificate-errors as a Chrome launch flag, causing TLS errors like ERR_SSL_PROTOCOL_ERROR to be rejected at the network layer before CDP could intervene (#1132)
• Fixed orphaned Chrome processes on daemon exit by spawning Chrome in its own process group and killing the entire group on shutdown. On Linux, PR_SET_PDEATHSIG ensures Chrome is killed even if the daemon is OOM-killed (#1137)
• Fixed CDP attach hang on Chrome 144+ when connecting to real browser sessions. Targets paused waiting for the debugger after attach are now resumed with Runtime.runIfWaitingForDebugger (#1133)
• Fixed stale daemon after upgrade silently reusing the old daemon process with broken CDP behavior. The daemon now writes a .version sidecar file and auto-restarts on version mismatch (#1134)
• Fixed stale daemon/socket recovery where close --all failed to clean up zombie daemons and stale files. Unreachable daemons are now force-killed and orphaned socket/pid files are removed (#1136)
• Fixed idle timeout not being respected because the sleep future was recreated on every select loop iteration, preventing the deadline from being reached (#1110)
• Fixed browser not relaunching when launch options change (e.g. adding extensions to config.json) between consecutive launch commands (#996)
• Fixed auto_launch() not honouring AGENT_BROWSER_PROVIDER for cloud providers, causing non-launch commands to fall back to local Chrome instead of connecting via the provider API (#1126)
• Fixed HAR capture missing API requests under heavy traffic by increasing the CDP broadcast buffer from 256 to 4096 events, reducing the drain interval from 500ms to 100ms, and enabling network tracking in cross-origin iframes (#1135)

Tests

• Fixed e2e_relaunch_on_options_change launching headed Chrome on CI where no display is available. The test now stays headless and only changes extensions to trigger the relaunch (#996)
• Fixed e2e_auth_login flake by reducing the SPA render delay from 1200ms to 800ms, giving more headroom within the selector wait window on slower CI runners
