* fix(xai): cap chat history at xAI 800-message limit
xAI returns 413 when messages/input exceed 800 items. Token
compression never fires on a long tool loop that still fits the
context window, so trim at the executor edge after Responses
expansion and drop orphaned tool pairs from the cut.
* chore(changelog): attach PR number to xAI 800-message fragment
* fix(xai): resolve TS2339 generic assignment in capXaiRequestHistory
Drop the T extends Record<string, unknown> generic on
capXaiRequestHistory and type it directly as
Record<string, unknown> -> Record<string, unknown>. Assigning
next.messages / next.input onto a generic T was rejected by
TypeScript even though every call site already passes/consumes a
JsonRecord (= Record<string, unknown>), so no caller relied on the
generic preserving a narrower type.
