Validate token items and their parameters before projecting exact declared policy tokens. Keep malformed and non-token values unknown; retain separate grammar for other policy headers.
Validation: real pinned Chrome public CLI baseline/candidate, 101 focused checks and 90 overlapping final checks, 834 upstream item-vector adaptations with two permitted refusals, check:fast and docs:check. Other browser/platform and policy-specific MCP delivery unverified; no performance measurement. Refs #4677.
Parse CDP repeated field lines independently before applying URI and quoted-parameter delimiters. Preserve declaration order and derive agent hints from retained links.
Validation: real pinned Chrome public CLI baseline and candidate each captured three responses per fixture; repeated Document links/hints restored and comma/single/Fetch controls unchanged. Three source controls failed before the fix. Sixty-one focused checks plus fifteen overlapping final network checks, check:fast and docs:check passed. No performance measurement or other browser/platform claim. Refs #4679.
* fix(browser): keep malformed Content-Length declarations unknown
Response metadata normalized Content-Length with Number(), truncation and
clamping, so "-5", "0x10", "1e3" and "+12" became observed lengths 0, 16,
1000 and 12. RFC 9110 section 8.6 defines the field as 1*DIGIT; any other
spelling declares no length. Parse only decimal digits within the safe
integer range and keep every other value null.
Fixes#2596

* test(browser): cover the largest accepted Content-Length
Pin the safe-integer boundary beside the overflow case so a future change
cannot reject the largest representable declared length unnoticed.
