Decompose src/wrap.rs to meet 400-line limit

[coderabbitai]

Description

The file src/wrap.rs contains 428 lines, exceeding the 400-line guideline from coding guidelines. Extract additional helpers into submodules to improve cohesion and comply with the file-length constraint.

Tasks

• Extract wrap_preserving_code and related inline-code helpers (determine_token_span, merge_code_span, extend_punctuation, looks_like_link, is_whitespace_token, is_inline_code_token, is_trailing_punct, attach_punctuation_to_previous_line) into a new submodule src/wrap/inline.rs
• Extract paragraph-level helpers (flush_paragraph, handle_prefix_line, append_wrapped_with_prefix) into src/wrap/paragraph.rs
• Update src/wrap.rs to declare mod inline; and mod paragraph;
• Update src/wrap.rs to use inline::wrap_preserving_code and paragraph::{flush_paragraph, handle_prefix_line} where needed
• Adjust visibility to pub(super) or pub(crate) as appropriate
• Run cargo test to ensure the refactored modules compile and all tests pass

@coderabbitai looking at the codebase, is this issue still relevant? If the issue has been fixed in the code, does the documentation reflect this?

If it is still relevant, please provide an assessment of the issue criticality (critical, high, medium or low), based on risk of the issue impacting the user and the anticipated blast radius.

Once a decision has been made, apply the appropriate label.

If the issue is documentation ONLY (i.e., no code changes needed), apply the documentation label in addition to the appropriate criticality label.

Please also provide an impact of the required changes.

[coderabbitai]

The refactoring described in this issue has been completed. The file src/wrap.rs now contains 175 lines (down from 428), and helpers have been successfully extracted into submodules src/wrap/inline.rs (194 lines) and src/wrap/paragraph.rs (84 lines). All files are now compliant with the 400-line guideline.

@leynos, this issue is no longer relevant and has been fully resolved in the codebase.

Current State

The refactoring described in issue #240 has been completed:

• src/wrap.rs now contains 175 lines (down from 428 lines)
• src/wrap/inline.rs exists with 194 lines (inline-code helpers extracted)
• src/wrap/paragraph.rs exists with 84 lines (paragraph-level helpers extracted)
• Additional submodules were also created: block.rs, fence.rs, line_buffer.rs, tokenize.rs, and tests.rs

All files are now compliant with the 400-line guideline.

Documentation Status

The documentation is accurate and up-to-date. Both CRUSH.md and AGENTS.md correctly document the 400-line limit:

Keep file size manageable. No single code file may be longer than 400 lines.

Recommendation

This issue should be closed as completed. All tasks listed in the issue description have been successfully implemented.
