docs: audit commands page

[demengc]

Summary

• Fixed broken link: text-localization.md corrected to text-and-localization.md
• Fixed incorrect Lamp 4.x annotations: replaced nonexistent @SuggestionProvider with the actual @Suggest (static literals) and @SuggestWith (dynamic class-based) annotations
• Fixed suggestion registration API: changed providers.put("warps", ...) to the real SuggestionProviders.Builder.addProvider(Class, SuggestionProvider) method
• Updated dead external links: replaced foxhut.gitbook.io/lamp-docs URLs with https://github.com/Revxrsal/Lamp/wiki
• Improved information density: converted feature overview and annotation comparisons to tables, replaced generic headings with descriptive ones
• Removed filler: cut inline comments from code examples that described what the code does, removed transition phrases and decorative section dividers
• Updated frontmatter description to be more specific about what the page covers

Test plan

• Verify all internal doc links resolve correctly in GitBook
• Verify code examples use correct Lamp 4.0.0-rc.14 annotations and API
• Confirm markdown renders properly in GitBook preview
