fix(history): re-repair tool_use/tool_result pairing after truncation

Browse Source 
limitHistoryTurns() can slice in the middle of a tool_use/tool_result
pair, leaving orphaned tool_result blocks that the Anthropic API
rejects with "unexpected tool_use_id found in tool_result blocks".

Call sanitizeToolUseResultPairing() after truncation (only when
truncation actually removed messages) to repair any broken pairs.
Applied to both attempt.ts and compact.ts code paths.

Fixes #4367
