Detect classes in Ruby percent literals using angle brackets or custom delimiters

[lazerg]

Summary

Fixes #20386.

Ruby lets you close a %w/%W literal with any non-alphanumeric character, but the pre-processor only recognized [, (, {, # and a space. So %w<bg-green-400> and %w|bg-blue-400| were skipped and the classes inside them never made it into the output.

The boundary lookup now maps < to > alongside the other paired delimiters, and falls back to treating any other non-alphanumeric, non-whitespace character as its own closing delimiter.

Test plan

Added pre-processor and extraction cases for %w<…>, %w|…|, %w:…: and %w!…! in crates/oxide/src/extractor/pre_processors/ruby.rs. They fail on main and pass with this change.

Walkthrough

Ruby %w preprocessing now supports angle-bracket delimiters, nested angle brackets, and additional ASCII punctuation delimiters. It skips modulo expressions and treats backslashes as escapes only when they are not the delimiter. Tests cover preprocessing and extraction for supported forms. The changelog records the new class detection entry.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains; the previously reported nested-angle truncation is addressed by balancing inner <…> pairs before closing the outer literal.
