  1. feat: restrict formatting only to the edited line range for clang-format 

    When using the Edit tool, clang-format now only formats the specific lines
that were changed, rather than reformatting the entire file. This prevents
unrelated formatting changes from cluttering the diff.

Adds calculateChangedLines() to detect modified line ranges from diffs,
and updates clang-format to use --lines flag for targeted formatting.
Other formatters continue to format the entire file as before.

Closes #4603

  2. refactor(format): enhance range-based formatting implementation 

    Switch from line-based to exact character/byte range formatting with a
robust DiffRange class. This refactoring improves compatibility across
different formatters and adds comprehensive validation.

Changes:
- Replace line ranges with exact character and byte offset tracking
- Implement DiffRange class to encapsulate range logic and conversions
- Add support for Prettier (character offsets) and clang-format (byte offsets)
- Handle Unicode multi-byte characters correctly
- Merge adjacent ranges to reduce formatter invocations
- Add validation to fromJSON() for negative/invalid ranges
- Extract clampOffset() helper to reduce code duplication
- Remove unused toByteOffsets() method
- Cache Buffer.byteLength() calls to avoid redundant computation
- Fix duplicate getCachedByteOffsets() calls in merge()
