revert: remove route file updates and directive prologue handling

Reverting two sets of changes per maintainer feedback:

1. Route file updates - These auto-generated changes will be handled in a
   separate PR (TanStack#5772) to keep this PR focused on router-plugin fixes.

2. Directive prologue handling (insertAfterDirectives) - Maintainer indicated
   this wasn't necessary for the current use case.

This PR now contains only:
- ESLint fixes (removing unnecessary optional chaining)
- Snapshot updates (removing ./ prepending)
- .gitignore updates (test-results, .claude)
