Implement remaining Neo-Markor features: intelligence, organization, reliability, export, customization, file management

[Copilot]

User description

Implements all unchecked checklist items: wiki-links, frontmatter parsing, pinned/daily notes, undo/redo, HTML export, settings UI, and file management operations.

Note Intelligence

• FrontmatterParser — extracts YAML frontmatter (title, tags, date, pinned, extras) from --- blocks
• WikiLinkParser — detects [[target]] and [[target|display]] patterns with indices
• MarkdownHighlighter — AnnotatedString-based syntax highlighting for source mode (headings, bold/italic, code, links, wiki-links, blockquotes, tasks, strikethrough)

Organization

• Pinned notes — persisted in DataStore stringSetPreferencesKey, toggled via long-press on dashboard cards
• Daily notes — creates/opens YYYY-MM-DD.md from drawer, searches full file tree (not just recent 20)
• Recent files — now sorted by lastModified descending; FileNode extended with lastModified/sizeBytes

Editor Reliability

• Undo/redo — 50-level ArrayDeque stack in EditorViewModel, exposed as canUndo/canRedo StateFlows
• Format-aware — SUPPORTED_EXTENSIONS expanded to md, txt, json, yaml, yml, todo.txt
• Reading mode strips frontmatter via FrontmatterParser.stripFrontmatter()

Export

• markdownToHtml() in FileRepositoryImpl — full MD→HTML converter (headings, code blocks, tables, task lists, inline formatting, wiki-links)
• Share intent for both HTML and plain text from editor overflow menu

Customization (Settings Screen)

• Theme mode (System/Light/Dark) via SegmentedButton
• Dynamic color toggle (Android 12+)
• Accent color picker (6 presets stored as ARGB int)
• Corner radius slider with live preview card
• NeoMarkorTheme now accepts themeMode/accentColorArgb/dynamicColor params, read from StoragePreferences in MainActivity

File Management

• FileRepository expanded: deleteFile, renameFile, moveFile, createFolder, resolveWikiLink
• FileBrowserScreen: long-press context menu (rename/move-to/delete), create folder button
• Format-specific icons for .json, .yaml

Tests

• FrontmatterParserTest (10 cases), WikiLinkParserTest (8 cases), MarkdownHighlighterTest (9 cases)

Security Fixes

• HTML escaping includes single quotes (') to prevent XSS in generated HTML
• StoragePreferences.isPinned fixed to use data.first() instead of edit for reads

Prevent source deletion when move copy fails

moveFile deletes the original document unconditionally even though the copy step is guarded by nullable stream opens (openInputStream(...)? and openOutputStream(...)?). If either stream cannot be opened (e.g., transient SAF/provider failure or write error), the copy is skipped but sourceDoc.delete() still runs, which can silently destroy the original file and leave an empty or partial destination.

Parse frontmatter blocks that end at EOF

The frontmatter regex requires a newline after the closing --- (...\n---\s*\n), so valid files whose YAML frontmatter ends at end-of-file without a trailing newline are treated as having no frontmatter. This breaks extractFrontmatter and stripFrontmatter for a common Markdown formatting case.

Render highlighted text in markdown source mode

SourceEditor computes highlightedText for Markdown content but never uses it when rendering the editor, so source mode still shows plain text despite the highlighter work running on each recomposition. This means the newly added syntax-highlighting feature is effectively non-functional.
