Subject: [PATCH] fix(compression): enable OmniGlyph for Claude Fable 5
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Rebuilt clean on release/v3.8.49 (branch forked from an old main and carried
~68 files of base drift). Reconciled with #7237 on the tip: supportsVision
keeps the authoritative getResolvedModelCapabilities() resolution (the PR's
isVisionModelId heuristic predates that fix); the PR's real change lands —
OAuth 'claude' now counts as a direct Anthropic transport for OmniGlyph, and
claude-fable-5 joins the vision model ids. Plumbing test now pins the
'|| provider === "claude"' invariant instead of exact formatting.
