v0.14.0 — track aicodebox v0.14.0, buffered SSE for tool/schema streaming stream:true for tool-calling and schema modes no longer returns 400 — the base computes the full answer non-streamed and replays it as a single-shot SSE stream (opening role chunk -> one content/tool_calls delta -> finish chunk -> [DONE]). Plain chat still streams incrementally as before. Genuine failures still surface as HTTP errors rather than a stream. PiAdapter unchanged — the buffered-SSE replay is entirely base-side. Base pinned to psyb0t/aicodebox:v0.14.0. Breaking for callers that special-cased the old 400. Minor bump. 49/49 tests green. Built against psyb0t/aicodebox:v0.14.0.
