prompt(agents): teach agent prompts to use comment suggestedText fixes (#315)

- editorial roles (ru/en): proofreader and line editor attach suggestedText
  replacements to targeted fixes; fact-checker ALWAYS attaches the ready
  correction for [Incorrect] verdicts; structural editor and narrator get a
  light-touch rule for in-place rewordings; role versions bumped and the
  content-hash lock refreshed
- MCP SERVER_INSTRUCTIONS: route 'propose a concrete text fix for one-click
  human approval' to create_comment with suggestedText (unique-selection
  reminder); build/ artifacts rebuilt
- AI-chat SAFETY_FRAMEWORK: mention the comment-suggestion capability so the
  default assistant offers ready fixes instead of only describing changes

Checks: catalog check.mjs OK; @docmost/mcp tests 448/448; server
ai-chat.prompt spec 28/28.
