Praveen K Palaniswamy 65e81158ab fix(ollama): route models by advertised capability (#11088)
Landed with the design call resolved per the owner's pick — **option 1**: the synced store is now endpoint-agnostic (persistDiscoveredModels and managedModelImport no longer drop non-chat models at write time), and chat selectability moved to read time (auto-pool expansion in autoStrategy applies filterChatSelectableModels; the models-route projection already had its chatOnly filter). Your discovery test now passes end-to-end (3/3): /api/show capabilities persist per connection and image/embedding requests route through the advertising host.

Reconciliation notes: conflicted areas merged onto the current tip (adobe discovery import, requestedModel preflight signature, resolvedProvider fast-path coexists with the synced-route override — explicit resolution wins); carried base-red drains (#10055 memoization, #11071 test variants) dropped as already-landed; the managed-model-import exclusion test was propagated to the new contract (image/video models persist; the read filter still hides them from chat pickers — pinned by a new assertion). Full battery: 205/206 focused (the one red is a confirmed periodic-timer timing flake on the loaded devbox — 20/20 isolated), autoCombo vitest 30/30, combo suites 46/46, gates + typecheck clean.

Thank you @yourspraveen — the capability probe + routing design was right; it just needed the store contract opened up. Fixes #11087.

/**
* Regression guard for GCF root-array surplus (SPEC Section 13).
*
* The root-array decode discarded parseArrayFromHeader's `consumed` count, so a wire whose
* declared count was fewer than the rows actually present silently dropped the surplus rows
* (the row loop breaks at the declared count and the extra lines were never read). SPEC 13
* makes a count mismatch — fewer OR more items than declared — an error. The fix checks that
* the consumed lines cover the whole document and throws otherwise.
*
* Reachable in prod: headroomEngine round-trips the encoded blob; a truncated decode is a
* silent losslessness violation.
