v0.9.0 — web-aware core + opt-in web-check
Ships the web layer as a single unified version — web-check off by default.
Core becomes web-aware (strict improvement). repair/check ignore web links (is_web_href guard); web anchors use a distinct <!-- web-uuid: X --> marker (never the core's <!-- uuid: X -->), so any repo's core gate stays green next to a cross-repo web link.
web-check subcommand (EXPERIMENTAL, opt-in). Anchors/verifies cross-repo GitHub web links against the destination's uuid. web-check PATH --online — tokenless for public destinations; a private destination without $GITHUB_TOKEN is web_unverifiable and never fails the build. Nothing runs without web-check + --online. No new dependency (stdlib urllib).
Constitution v1.1.0: single sanctioned network carve-out for --online; default path stays offline/deterministic.
