🐎 ci(#126): ls-lint media file

[naoki-00-ito]

This pull request primarily updates image file naming conventions across the codebase to use kebab-case, and adjusts the .ls-lint.yml configuration to enforce these conventions for several file types. It also fixes image path references within markdown and TypeScript files to match the new naming scheme. These changes improve consistency and maintainability in file organization and linting.

File naming and linting configuration:

• Updated .ls-lint.yml to enforce kebab-case for image files (.png, .jpg, .jpeg, .svg, .ico) and .txt files, and corrected the directory rule to .dir: kebab-case. Also added .astro to the ignore list. [1] [2]

Image path and reference fixes in content and data files:

• Updated image path references in src/content/blog/codeblue2025-summary-repo.md and src/content/blog/mitmproxy-doc-read-01.md to use kebab-case file names, ensuring they match the new naming convention and preventing broken links. [1] [2] [3] [4] [5]
• Updated the image file name in the src/data/product.ts product list for Meeats BoardGame & Kitchen to use kebab-case.
