CodeLedger v1.4.2

Added

• Analytics: Monthly activity chart — AnalyticsView now shows a rolling 12-month bar chart of solve activity alongside the existing weekly chart.
• Analytics: Day-of-week heatmap — New bar chart showing which day of the week you solve most; peak day is highlighted and surfaced as a "Best Day" stat.
• Analytics: Rolling 7/30-day counts — last7Days and last30Days replace the previous calendar-week/month counters so the numbers always reflect a true rolling window.
• Floating AI: Guided (Socratic) mode — Default panel mode now leads the learner through questions instead of handing over the answer. A "Guided / Direct" toggle chip in the panel header lets you switch modes; selection is persisted to storage.
• Floating AI: Apply-code button — AI-suggested code blocks now render an "Apply" button that writes the code directly into the active Monaco editor without copy-paste.
• Floating AI: Alt+` keyboard hint — Keyboard shortcut hint displayed in the panel title bar.
• Floating AI: Improved Monaco code extraction — getActiveCodeEditor() is tried first, then getEditors(), then getModels(), then DOM view-lines sorted by top CSS value for correct ordering; covers all LeetCode editor states.
• Conflict Resolution Modal: SameCodeStep — When both versions have identical (normalised) code, the modal shows a compact three-way choice (local / remote / both) with an 8 s auto-resolve countdown and progress bar.
• Conflict Resolution Modal: DiffApproachStep — When code differs the modal shows a three-way choice with per-side metadata (difficulty, language, date, AI review status, tag count) and the fields that differ.
• PanelAI: Queue management controls — Settings → AI now polls and displays real-time review queue stats; exposes "Queue Missing Reviews", "Requeue All", and "Cancel" actions.
• AIReviewPanel: QueueStatusCard — Inline status card in the review panel shows queue depth, snail-mode pause state, and time-to-next-batch.
• Service worker: Snail Mode state — Persistent snailMode state (lastBatch, consecutiveErrors, isPaused, pausedUntil, totalProcessed, totalErrors) tracks AI review batch throttling across browser restarts.
• Popup: settingsTab deep-link — openLibrary() accepts a settingsTab parameter to deep-link directly to a Settings sub-panel from the popup.
• DedupReviewQueue: "Let AI Decide" action — Per-conflict button that requests an AI comparison and auto-resolves within 10 s timeout; default countdown reduced from 12 s to 5 s.

Fixed

• AI prompts: chatMode respected — buildConversationSystemPrompt() now switches to the direct-answer prompt when context.chatMode === "direct", preventing Socratic rules from leaking into Direct mode sessions.
• Floating AI: DOM line sort — View-lines are now sorted by style.top before joining, fixing incorrect line ordering when code spans the visible scroll window.
