Subject: [PATCH] v0.27.16: Increase document limit to 250K characters

The instruction field in writeRequestSchema was capped at 5,000 characters,
causing "Evolve Document" to fail when accumulated provocation responses
exceeded that limit. Raised to 250K. Also increased context-builder LIMITS
and hardcoded MAX_ANALYSIS_LENGTH values in routes.ts to support much larger
documents throughout the provocation pipeline.
