Summary by cubic

Loads markdown rules from ~/.continue/rules and .continue/rules into the CLI system message and config so always-applied rules are included automatically. Aligns with Linear CON-5301 by applying global and repo rules without extra flags.

• New Features
  • Scans both rules directories, parses markdown frontmatter, and includes non-invokable, alwaysApply rules.
  • Deduplicates against existing config and CLI rules before merging.
  • Adds rule metadata to config and injects rule text into the system message.

^{Written for commit 041541d. Summary will update on new commits.}
