Fix pre-commit hook to not stage unrelated working directory changes

[nearestnabors]

Summary

• Fix update-links section to not accidentally stage unrelated working directory changes
• Captures already-modified files BEFORE running update-links, then only stages newly-modified files

Problem

The update-links section was using git diff --name-only which captures ALL modified files in the working directory, not just files modified by the update-links script. This could accidentally stage files the user had modified but intentionally not staged for the current commit.

Test plan

• Modify an mdx file but don't stage it
• Stage next.config.ts with a new redirect
• Run commit - verify the unstaged mdx file is NOT automatically staged
• Verify files actually modified by update-links ARE staged

Note

Ensures the update-links step in .husky/pre-commit does not stage unrelated working changes.

• Captures ALREADY_MODIFIED files before running pnpm update-links, then stages only newly modified app/**/*.mdx|md|tsx files
• Adds count of staged files and warning output listing files skipped due to existing unstaged changes
• Prevents mixing user unstaged work with automated link updates; updates messaging accordingly
