Summary by cubic

Stop storing rule text in chat history and dev data. We now keep only rule metadata to reduce payload size and improve privacy, while keeping a quick way to open the full rule when needed.

• Refactors

  • appliedRules now uses RuleMetadata (no rule text) across core and GUI.
  • getSystemMessageWithRules returns metadata; rule text is used only to build the system message.
  • Removed rule text from analytics payloads and schema.
  • Added useOpenRule and updated RulesPeek and RulesSection to open the rule source (default URL for default-* rules, file for others).
  • Updated getRuleId and rules-utils to work with RuleMetadata.

• Migration

  • Remove any use of appliedRules.rule; open the source file or default URL instead.
  • Update types where appliedRules was RuleWithSource to RuleMetadata.
  • No user action needed; new chats no longer persist rule content.
