v0.3.4

Fixed

• README: corrected the hot-reload blanket claim for vision_* fields.
  The Hot Reload and Restart section previously stated that all vision_*
  fields require a server restart. This was inaccurate for the 7 intent-aware
  vision fields introduced in v0.3.2 (vision_intent_strategy,
  vision_decomposition_enabled, vision_decomposition_timeout_ms,
  vision_crafting_timeout_ms, vision_adjacent_text_max_chars,
  vision_recent_messages_count, vision_system_prompt_max_chars), which
  are hot-reloadable per src/config/reload.ts and marked
  restartRequired: false in the dashboard Config tab. The README now lists
  these 7 fields explicitly as hot-reloadable and qualifies the restart claim
  as applying to "most other vision_* fields."
