* feat: enhance HAR entries with timings, cookies, postData, and protocol normalisation
Extends #874's HarEntry struct and CDP handlers with richer capture:
- wall_time (f64) replaces pre-formatted started_date_time, preserving
sub-second precision from CDP wallTime for accurate RFC 3339 output
- request_headers / response_headers changed from Value to Vec<(String,String)>
for typed access without re-parsing JSON objects
- post_data captured from Network.requestWillBeSent for HAR postData
- cdp_timing and loading_finished_timestamp captured from responseReceived
and loadingFinished respectively, enabling har_compute_timings to produce
accurate blocked/dns/connect/ssl/send/wait/receive phases
- har_cdp_protocol_to_http_version normalises CDP protocol strings
(h2 -> HTTP/2.0, h3 -> HTTP/3.0, etc.)
- Request cookies parsed from Cookie header; response cookies from Set-Cookie
with ';'-first split to correctly strip Path/HttpOnly attributes before '='
- har_wall_time_to_rfc3339 replaces har_started_date_time, using the time
crate directly on the f64 epoch value
