Fixes #5322

Problem

For a fenced code block with CRLF line endings, deserializeMd kept a trailing \r on every code_line except the last, and serializeMd then wrote CRLF inside an LF fence.

Fix

The code_block deserialize rule split mdastNode.value on \n only. It now splits on \r\n, \r or \n, so CRLF/CR input gives the same value and serialized output as its LF version. LF input is unchanged.

Tests

Added codeBlockLineEndings.spec.ts covering CRLF and CR input: value equals the LF value, no \r in the value, serialize output equals the LF output. Patch changeset for @platejs/markdown included.

Verification

I have not run the spec or pnpm check locally (full monorepo checkout wasn't possible in my environment); relying on CI. The split pattern was checked in plain Node.

On top of the PR

• Kept
  • The CRLF and CR cases.
• Changed
  • The fix moved from the code_block rule to markdownToSlateNodes, so paragraphs, blockquotes, list items, inline code and math lose the carriage return too. That also fixes plate#5323 on main.
  • The test moved into deserializeMd.spec.ts. Each line ending's document, a fenced code block and a two-line paragraph, must parse to the value of its LF version.
  • The changeset names CR as well as CRLF and says the value changed, not serializeMd.
• Dropped
  • CODE_LINE_BREAK_REGEX and the code_block rule change, so defaultRules.ts matches main.
  • The test's check that the value holds no CR and its check of the serialized fence. The value comparison already fails on both bugs.

Verification

• The new test fails on the PR head for the paragraph and passes on my commit, for CRLF and CR.
• The @platejs/markdown suite, typecheck and lint pass on my commit.
