Add ZIO HTTP template2 support

[nafg]

Summary

• add a ZioHttpTemplate2 generator target backed by zio-http 3.11.3
• publish _ziohttp modules for Bootstrap 3/4/5, Bulma, Tabler, Semantic UI, Fomantic UI, and Font Awesome
• support chainable classes while preserving and normalizing existing template2 class attributes
• expose allocation-light C.* class-name values that compose with both vararg and collection forms of template2's className API without becoming text children
• avoid per-extension lazy-value state while retaining cached values on singleton C objects
• add cross-built rendering and compile-safety tests

Validation

• all 25 projects load and the ZIO HTTP targets compile on Scala 2.13.18 and 3.8.4
• tabler_ziohttp/compile passed on both Scala versions
• all 6 template2 integration tests passed on both Scala versions
• githubWorkflowCheck passed
• validated with master's Scalameta 4.16.0; the class attribute is represented as a synthetic Lit.String so managed-source rendering does not require tokenizing parsed quasiquote origins

Pull request overview

This PR extends the CSS DSL generator with a new ZIO HTTP template2 target, adding publishable _ziohttp modules across supported CSS frameworks and documenting usage, plus a new rendering test to validate class composition and attribute normalization.

Changes:

• Added a TargetImpl.ZioHttpTemplate2 generator target and wired it into code generation (support injection) for generated DSL modules.
• Introduced new *_ziohttp SBT subprojects for Bootstrap/Bulma/Semantic/Fomantic/Font Awesome, and updated README install coordinates generation to emit safe <version> placeholders on snapshots.
• Added a bootstrap3_ziohttp munit test suite covering chaining, C composition, and class-attribute preservation/normalization.

Review limit reached

@nafg, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 4 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
