Command references wrong file extension for guidelines

Medium Severity

The smart-commit.md command references .feverrules/rules/commit-guidelines.md and smart-pr.md references .feverrules/rules/pull-request-guidelines.md, but the ARCHITECTURE.md consistently documents these source files as having a .mdc extension (e.g., .feverrules/rules/commit-guidelines.mdc). When the AI executes these commands, it will attempt to read files at paths that likely don't exist, causing the guideline lookup to fail silently.
