Greptile Summary

This PR configures editor tooling, updates dependencies, and applies linting fixes across the codebase. The changes standardize code formatting using Ultracite/Biome and set up pre-commit hooks with Husky.

Major Changes:

• Migrated from direct Biome usage to Ultracite 7.0.4 CLI wrapper
• Added Husky for git hooks with pre-commit formatting automation
• Configured VSCode and Cursor editor settings for consistent formatting
• Updated biome.jsonc with file scope patterns and Ultracite core config
• Enhanced CI workflow with concurrency controls and better documentation
• Applied formatting fixes: quote style, semicolons, import ordering, trailing commas, EOF newlines
• Fixed email template placeholder links (# → / and /privacy-policy)

Critical Issue:

• .husky/pre-commit has bun test before the shebang, which will cause the hook to fail on execution

Confidence Score: 2/5

• This PR has a critical bug that breaks git pre-commit hooks
• The pre-commit hook has bun test before the shebang line, making it syntactically invalid and preventing commits. This must be fixed before merging. All other changes are safe formatting updates.
• .husky/pre-commit requires immediate attention - the shebang must be on line 1
