feat(markdown): render GitHub alert callouts as tinted cards

[rainxchzed]

README and release-notes blockquotes starting with `> [!NOTE]`, `[!TIP]`, `[!IMPORTANT]`, `[!WARNING]`, `[!CAUTION]` now render as tinted Material 3 Card with category icon + colored container, matching GitHub mobile. Today they show as literal text in a plain blockquote.

How

• Custom `blockQuote` slot via `markdownComponents(...)` on the Markdown call in About + WhatsNew
• `AlertBlockQuote` inspects node text; if first line matches the alert pattern, renders Card with icon (`Outlined.Info`/`Lightbulb`/`Campaign`/`Warning`/`Report`) and body via nested `Markdown(...)`. Else falls through to default blockquote
• 5 label strings × 13 locales

Test plan

• Android compile clean
• Device: open a repo with alert blockquotes (e.g. astral-sh/uv, vercel/next.js README) — verify all 5 kinds render as colored cards. Non-alert blockquotes still render as plain blockquote.

Summary by CodeRabbit

Release Notes

• New Features
  • GitHub-style alerts (Note, Tip, Important, Warning, Caution) in README and release notes now render as styled icon cards instead of plain text.
  • Manual app linking now automatically suggests matching GitHub repositories with ranked candidates.

Changes

GitHub Alert Block Rendering

Layer / File(s)	Summary
Markdown alert label strings core/presentation/src/commonMain/composeResources/values*/strings-*.xml	Five markdown alert label string resources (markdown_alert_note, markdown_alert_tip, markdown_alert_important, markdown_alert_warning, markdown_alert_caution) added across 13 language variants to provide localized UI text for alert headers.
Alert block rendering component feature/details/presentation/src/commonMain/kotlin/zed/rainxch/details/presentation/markdown/AlertBlockQuote.kt	GithubAlertKind enum with regex parser extracts alert type from blockquote start; AlertBlockQuote composable renders matched alerts as colored Surface cards with icons and localized labels, delegates non-alerts to fallback; helper functions map alert kind to palette/icon/label.
Custom markdown components factory feature/details/presentation/src/commonMain/kotlin/zed/rainxch/details/presentation/markdown/GithubStoreMarkdownComponents.kt	githubStoreMarkdownComponents(imageTransformer) returns MarkdownComponents with custom blockQuote renderer using AlertBlockQuote and fallback handling.
Integration into detail sections feature/details/presentation/src/commonMain/kotlin/zed/rainxch/details/presentation/components/sections/About.kt, WhatsNew.kt	Markdown composables in ExpandableMarkdownContent now receive custom components argument from githubStoreMarkdownComponents(imageTransformer), enabling alert rendering in both sections.
Release notes documentation core/presentation/src/commonMain/composeResources/files/whatsnew/*/18.json	Release notes across 13 languages updated to document GitHub alert styling and manual app linking improvements in version 1.8.3.
