On Windows the daemon derives a TCP port from the session name via a
djb2 hash (e.g. "default" → 50838). On many machines this port falls
inside Hyper-V's excluded port range (winnat), causing EACCES on bind
and preventing the daemon from starting.
Changes:
- daemon: try the hash-derived port first; on failure, bind to port 0
(OS-assigned) and write the actual port to the .port file
- client (connection.rs, stream.rs): read the .port file to discover the
daemon's actual port, falling back to the hash if the file is absent
- run_daemon: guard .sock file operations with #[cfg(unix)] and add
.port file cleanup for #[cfg(windows)]

* fix: re-apply download behavior on recording context (#1019)
* fix: re-apply download behavior on recording context
record start creates a new browser context via Target.createBrowserContext.
Browser.setDownloadBehavior called at launch only applies to the default
context, so downloads in the recording context are silently dropped.
Fix:
1. Store download_path on BrowserManager (from LaunchOptions)
2. After creating the recording context, call Browser.setDownloadBehavior
with the new browserContextId
This ensures downloads work during recording.
Fixes#1018
* fix: add download_path to third BrowserManager constructor (auto_connect_cdp)
* fix: reap zombie Chrome process and fast-detect crash for auto-restart (#1023)
When Chrome crashes (e.g. SIGTRAP from CHECK() assertion), the daemon
now:
1. Reaps the zombie immediately via a SIGCHLD handler in the event loop
that calls waitpid(-1, WNOHANG)
2. Detects the crash instantly on the next command via a non-blocking
try_wait() check (has_process_exited), avoiding the 3-second CDP
timeout that is_connection_alive() would incur
3. Auto-relaunches Chrome transparently for the caller

* fix: route keyboard type through text input (#1014)
* fix: handle --clear flag in console command (#1015)
The console and errors commands parsed --clear from CLI args but the
action handlers silently ignored the flag. The handlers did not accept
the cmd parameter so they had no way to read the clear field.
Changes:
- Add clear_console() method to EventTracker in network.rs
- Update handle_console to accept cmd, read the clear field, and clear
the buffer when --clear is passed (returns {cleared: true})
- Update call site in execute_command to pass cmd

* fix: retain radio/checkbox elements in compact snapshot tree (#1008)
compact_tree() checked for "[ref=" to identify lines worth keeping, but
radio and checkbox elements render as e.g. [checked=false, ref=e1] where
the "[" opens before "checked=", not "ref=". Dropping the leading bracket
so the check is just "ref=" fixes the match for all elements with refs.

* fix: restore WebSocket streaming in native daemon
The v0.20.0 Rust rewrite broke WebSocket streaming — connections opened
but received zero messages before closing. Multiple issues contributed:
1. StreamServer was dropped immediately after creation in daemon.rs,
closing the broadcast channel and killing all WS connections.
2. Screencast frames were only processed during command polling
(drain_cdp_events) instead of in real-time, unlike the 0.19.0
TypeScript cdp.on('Page.screencastFrame') callback.
3. Auto-start/stop screencast on WS client connect/disconnect was
missing from the Rust implementation.
4. Screencast CDP commands used the wrong session ID (daemon session
name instead of the CDP page session from Target.attachToTarget).
5. Broadcast channel Lagged errors killed WS connections instead of
being handled gracefully.
The fix adds a background CDP event loop in StreamServer that subscribes
to Chrome events and broadcasts screencast frames in real-time, properly
tracks the CDP page session ID, restores auto-screencast lifecycle, and
keeps the StreamServer alive in DaemonState.
Fixes#820
* fix: use actual CDP session ID for input dispatch in stream WebSocket
Pass the real cdp_session_id (from Target.attachToTarget) through to
handle_ws_client instead of an empty string. Previously, input commands
(mouse, keyboard, touch) were sent with `"sessionId": ""` which Chrome
silently rejects. Now the correct page session ID is read at dispatch
time, and when no session ID is set yet (before browser launch),
the field is omitted entirely via `None` so Chrome uses browser-level
dispatch.

Replace all `eprintln!` calls in daemon-context code with
`let _ = writeln!(std::io::stderr(), ...)` so that broken pipe errors
on stderr are silently ignored instead of panicking.
The CLI client spawns the daemon with piped stderr to capture startup
errors, then drops the pipe handle once the daemon is ready. Any
subsequent `eprintln!` in the daemon panics because Rust's `eprintln!`
macro internally unwraps the write result. This caused the reported
"failed printing to stderr: Broken pipe (os error 32)" panic during
Chrome launch on Linux.
Closes#799

The client (connection.rs) and native daemon (native/daemon.rs) used
different get_port_for_session() implementations on Windows:
- Client: i32, .chars(), djb2 — (hash << 5) - hash + c
- Daemon: i64, .bytes(), Java hashCode — hash * 31 + b
For session name "default", client computes port 50838 while the
daemon binds on 51174, causing a 5-second timeout and startup failure.
Fix: align native/daemon.rs to use the identical djb2 algorithm from
connection.rs (i32, chars, djb2), so both sides agree on the port.
Unix is unaffected (uses Unix domain sockets, no port hashing).
Tests: add port hash regression tests to all three implementations
(native/daemon.rs, connection.rs, daemon.ts) to prevent future drift.
Fixes#705
