fix: fold stacked image size comments

[ocavue]

An image now folds the whole run of magic comments chained behind it (first one wins) and stripMagicComment drops the whole run, so documents where an unfolded rewrite once stacked a second comment render clean and collapse back to a single comment on the next resize. walk and walkResolvedLink now share one walkAtomChild dispatch so atom handling cannot drift between the top level and a link label again; adds parser, resize round-trip, and MarkdownView coverage for linked images.

Summary by CodeRabbit

• Bug Fixes
  • Improved image resizing when images are placed inside links.
  • Preserved link destinations while updating image dimensions.
  • Consolidated consecutive image size comments into a single effective setting.
  • Ensured image metadata comments are handled consistently in linked and embedded content.
  • Corrected comment placement so content following linked images remains associated with the surrounding link.
• Tests
  • Added coverage for linked image resizing, metadata handling, and rendered image previews.

📝 Walkthrough

Walkthrough

Linked-image handling now uses shared atom traversal and supports consecutive magic-comment folding. Tests cover resizing, parsing, link-label behavior, comment placement, and rendered image width.

Changes

Linked image metadata handling

Layer / File(s)	Summary
Atom traversal and comment folding packages/core/src/extensions/inline-text-to-mark-chunks.ts, packages/core/src/extensions/magic-comment.ts	Atom processing is centralized for wikilinks, wiki embeds, and images. Resolved link labels skip consumed children. Consecutive image metadata comments are folded while preserving the first parsed metadata.
Core linked-image regression coverage packages/core/src/extensions/image.test.ts, packages/core/src/extensions/inline-text-to-mark-chunks.test.ts, packages/core/src/extensions/magic-comment.test.ts	Tests cover linked-image resizing, stacked comments, comment precedence, folding boundaries, and removal of trailing comment runs.
Parser and renderer validation packages/markdown/src/inline.test.ts, packages/react/src/components/markdown-view.test.tsx	Markdown tests verify comment placement within links. React tests verify linked-image width rendering.
