AI Summary

This release implements the style scope hash improvements to ensure unique and secure hashing for scoped styles.

Key Highlights

Improved style scope hash uniqueness to prevent collisions
Switched hashing algorithm from djb2 to truncated SHA-256
Added requirement for `filename` parameter in parsing functions

Breaking Changes

The `filename` parameter of `parse`, `parseModule`, and per-target `parse` wrappers is now required (typed as a non-empty string).

New Features

Enhanced style scoping with unique hashes per file and block
Implementation of truncated SHA-256 hashing

Full Release Notes

### Patch Changes

- [#1260](https://github.com/Ripple-TS/ripple/pull/1260)
  [`b1256fd`](https://github.com/Ripple-TS/ripple/commit/b1256fdb5bf279ee7dd20bf1a71dcfccc47e279c)
  Thanks [@leonidaz](https://github.com/leonidaz)! - Make style scope hashes
  unique per style block and per file. The hash was derived from the style block's
  content alone, so two `<style>` blocks with identical CSS — in different
  components of the same file, or in different files — collided and shared a
  scope. The hash input now includes the filename and the line/column where the
  `<style>` tag starts. Because the filename may be an absolute path, the hash
  also switched from the reversible djb2 hash to the truncated SHA-256 hash so
  file structure can't be recovered from class names in the shipped bundle.

  The `filename` parameter of `parse`, `parseModule`, and the per-target `parse`
  wrappers is now required (typed as a non-empty string), and parsing a `<style>`
  element without one throws a clear error instead of silently seeding the hash
  with an empty name. The prettier plugin and eslint parser pass their host's file
  path through, falling back to a plugin-specific placeholder when formatting or
  linting in-memory text.
