📦🔧：respect escaped code-span delimiters

[DerekNonGeneric]

Escaped opening backticks were incorrectly converted into code spans.

This respects backslash parity for openers, handles an escaped first backtick
inside a longer run, preserves raw closing-run behavior inside a span, and adds
escape-parity and linear-time regressions.

Fixes #97.

Summary by CodeRabbit

• Bug Fixes
  • Improved Markdown code-span conversion when opening backticks are preceded by backslashes: odd and even runs are handled correctly, and escape backslashes are preserved.
  • Backslashes before closing backticks remain part of the code text, and matching continues correctly after escaped openings.
  • Long inputs with escaped backticks continue to be processed efficiently.

📝 Walkthrough

Walkthrough

The code-span helper now distinguishes escaped opening backtick runs by the parity of preceding backslashes. It updates matching and rendering behavior, with tests for escaped delimiters and a performance case.

Escaped delimiter matching and validation packages/util-text/src/helpers/md-code-spans-2-html.ts, packages/util-text/test/helpers/md-code-spans-2-html.ts, .changeset/escaped-code-delimiters.md	The helper tracks backslash parity before opening backtick runs, adjusts matching for escaped runs, and preserves the preceding backslash in rendered text. Tests cover escaped delimiters and a 100,000-repetition performance case. A patch changeset records the update.
