* fix(browser): keep negative script columns Chrome reports Chrome reported a Debugger.scriptParsed event with startColumn -60 and endColumn -15 for an inline script in WordPress's helper frame. CDP declares these columns as plain integers, but REA's admission required min(0), so one script failed the whole observe-web-execution run with unreadable_output. CDP resource columns now share one representation, cdpResourceColumnSchema, for script start/end columns, initiator call frames, parser initiators and event listeners. Positions on a script's first line include its start column, so keeping the reported values keeps the documented script-relative conversion consistent. The domain contract and web runtime docs state that a negative column does not locate a column in the resource. Fixes #8674 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(browser): apply the CDP column policy to passive capture inspect_web_page and discover_webmcp_tools still read CDP columns through cdpSourceCoordinates, whose own >= 0 check turned a negative column into null and reported invalid_protocol_value. WebMCP discovery also dropped the tool's whole registration_source. cdpResourceColumnSchema now lives with the domain's CDP observation schemas. Runtime admission, the passive coordinate helper and the runtime, console, initiator and WebMCP output schemas all use it. Lines keep their non-negative rule.
