refactor: add generic wrap Twig filter to dedupe comment-wrapping logic

[KevalPrajapati]

Closes #1479 (partially — see scope below).

The same wordwrap() + prefix logic was copy-pasted across ~8 comment filters. This adds one wrap(width, prefix) filter in SDK.php and points the existing call sites at it, then deletes the duplicates.

Removed: comment1, comment2, dartComment, dotnetComment, swiftComment, rubyComment. Also dropped comment3, which wasn't referenced by any template.

Templates now call e.g. {{ method.description | wrap(75, ' /// ') }}, with the prefix at the call site instead of buried in PHP.

No output change

This is a straight refactor — I kept the width at 75 and the exact prefixes, so the generated SDKs come out identical. I verified by generating every SDK before and after the change and diffing the output directories (all 24 match). git diff alone isn't enough here since examples/ is gitignored.

Added a few unit tests for the new filter — there weren't any covering this before.

Left for follow-ups

• Go and Rust also have their own versions, but they trim() and take an indent argument, so wrap would need a couple of extra params. Didn't want to widen the API in the same PR.
• The inline replace({"\n": ...}) templates (Kotlin, Android, Python, etc.) mentioned in the issue — those don't word-wrap today, so switching them to wrap would change their output. That's a behavior change, not a no-op, so it makes more sense as its own PR.

Happy to fold those in here instead if you'd prefer one bigger PR.

Greptile Summary

This PR consolidates ~8 duplicated comment-wrapping Twig filters into a single generic wrap(width, prefix) filter registered in SDK.php, then updates every call site to use it. The removed filters (comment1, comment2, comment3, dartComment, dotnetComment, swiftComment, rubyComment) all had identical structure — split on newlines, prefix . wordwrap(line, 75, "\n" . prefix), rejoin — so the new filter is a faithful drop-in replacement.

• New filter (SDK.php): wrap(int $width = 75, string $prefix = '') is registered as a global Twig filter with is_safe => html, matching the safety annotation of every filter it replaces.
• Template updates (12 files): All 12 changed templates now pass the prefix at the call site (e.g. | wrap(75, ' /// ')); no template still references any of the removed filter names.
• Removed language filters: Dart.php, DotNet.php, Ruby.php, Swift.php, and Web.php each lose one or two filter registrations with no replacement needed.

Confidence Score: 5/5

This is a pure deduplication refactor — the generated SDK output is unchanged and all call sites have been updated correctly.

Every removed filter has been replaced by wrap with the identical prefix string and width of 75. A grep across all templates confirms no stale references to the old filter names remain. The new filter adds a defensive (string) cast over the originals and carries the same is_safe => html annotation. There are no behavioral differences on any code path exercised by the templates.

No files require special attention.

src/SDK/Language/Swift.php	Removes swiftComment filter; prefix ' /// ' preserved at swift and apple template call sites.
src/SDK/Language/Web.php	Removes comment2 and unreferenced comment3; comment2 prefix ' * ' preserved in react-native template call sites.
templates/dart/lib/services/service.dart.twig	Replaces dartComment with wrap(75, ' /// ') at both the service description and method description sites; the split/join pipeline that trims extra leading spaces is preserved.
templates/flutter/lib/services/service.dart.twig	Same dartComment → wrap(75, ' /// ') swap as the dart template; both call sites updated consistently.
templates/deno/src/services/service.ts.twig	Replaces comment1 with wrap(75, ' * '); prefix and width match the original exactly.
templates/php/src/Services/Service.php.twig	Replaces comment1 with wrap(75, ' * '); functionally identical to the removed global filter.
templates/dotnet/Package/Services/ServiceTemplate.cs.twig	Replaces dotnetComment with wrap(75, ' /// '); prefix matches the removed filter verbatim.
templates/unity/Assets/Runtime/Core/Services/ServiceTemplate.cs.twig	Replaces dotnetComment with wrap(75, ' /// '); identical prefix to the dotnet template change.
templates/ruby/lib/container/services/service.rb.twig	Replaces rubyComment with wrap(75, ' # '); prefix matches original 8-space Ruby comment prefix.
templates/apple/Sources/Services/Service.swift.twig	Replaces swiftComment with wrap(75, ' /// ') at both method description sites; prefix matches original 4-space Swift doc-comment prefix.
templates/swift/Sources/Services/Service.swift.twig	Replaces swiftComment with wrap(75, ' /// ') at both method description sites; identical to the apple template change.
templates/react-native/src/services/template.ts.twig	Replaces comment2 with wrap(75, ' * '); prefix matches the original comment2 exactly.
templates/react-native/src/client.ts.twig	Replaces comment2 with wrap(75, ' * ') for header descriptions; functionally identical.
