Phase 3, Task 13: Remove buffered mode from HtmlRewriterAdapter #588
Description
Parent: #563
Depends on: Tasks 11, 12
Summary
With all script rewriters fragment-safe, the `new_buffered()` constructor and the `buffered` flag in `HtmlRewriterAdapter` are no longer needed. Remove the dual-mode complexity.
Changes
- Delete `HtmlRewriterAdapter::new_buffered()`
- Remove `buffered: bool` field and `accumulated_input: Vec`
- Remove the `if self.buffered` branch in `process_chunk()`
- Delete `lol_html_fragments_text_across_chunk_boundaries` test (documents the problem, no longer needed as a gate)
