Walkthrough

This pull request renames multiple source files in the signup-form app from PascalCase to kebab-case and updates all corresponding import paths to match (e.g., AppContext.tsx → app-context.tsx, FormPage.tsx → form-page.tsx). Adds an ESLint rule ghost/filenames/match-regex enforcing the filename pattern ^[a-z0-9.-]+$. Updates apps/signup-form/package.json version and adds a Release section to apps/signup-form/README.md. No runtime logic, control flow, or public API changes.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10–15 minutes

• Validate import path updates across all renamed files (multiple files under apps/signup-form/src — ~13+ changes).
• Confirm ESLint rule configuration (ghost/filenames/match-regex with ^[a-z0-9.-]+$) is intentional and consistent with repository conventions.
• Verify apps/signup-form/package.json version bump and README release instructions are correct and complete.
