On slow CI machines, _get_pending_network_requests() can hang for 15s+
when Chrome is busy loading/rendering after a navigation. This silently
eats into the 30s BrowserStateRequestEvent budget, leaving insufficient
time for the actual DOM capture — causing 5 consecutive timeouts and
agent termination.
Observed on eBay search results in eval runs: DOMWatchdog started but
produced zero log output for 15 seconds before the timeout killed it.
The pending network check was the first await after the URL log.
- AGI-569: after any click that opens a new tab, automatically dispatch
SwitchTabEvent so the agent lands on the new page immediately instead
of requiring a manual switch step (~877 occurrences)
- AGI-548: for <input type="checkbox/radio">, capture checked state
before the CDP mouse click and verify it toggled afterward; if
unchanged (custom-styled or shadow-DOM-backed inputs), fall back to
JS element.click() and report the final checked state in metadata
(~1,241 occurrences)
- Introduced type aliases for captcha results to improve clarity and maintainability.
- Updated event handler signatures to use specific event types from the CDP module.
- Ensured consistent typing for captcha result attributes within the CaptchaWaitResult class.
- Added assertion for timeout handling in the captcha waiting logic.
- Add 0-byte file check in upload_file handler to catch empty files early
with a clear error message instead of silently passing them to websites
- Add 0-byte file check in CDP upload watchdog before setFileInputFiles
to prevent uploading empty files that cause cascading failures
- Replace hardcoded text extension list in read_file_structured() with
dynamic derivation from _file_types, so new text-based file types
are automatically supported for external file reading

CDP's dispatchKeyEvent doesn't trigger beforeinput events that Draft.js
relies on for text input. This causes the first character to be dropped.
Solution: Detect Draft.js editors via specific DOM attributes (DraftEditor
class, data-contents, data-block, data-offset-key) and prepend a sacrifice
space character that Draft.js will drop, preserving the actual text.
