Rewrite/tauri svelte

[Splode]

Complete Rewrite — Electron → Tauri 2 + Rust + Svelte 5

Pomotroid has been rebuilt from the ground up. The Electron + Vue.js stack has been replaced with a fully native Tauri 2 application backed by Rust and a Svelte 5 frontend, resulting in a drastically smaller footprint, faster startup, and no Chromium dependency.

Timer

• Drift-correcting engine — Rust timer thread uses std::time::Instant with a fixed tick schedule; eliminates the cumulative drift that plagued the web-worker approach
• Sleep / wake handling — timer pauses automatically on OS sleep and resumes from the correct position on wake; no missed rounds
• Round sequencing — configurable work / short-break / long-break cycle with independent auto-start per round type
• Skip and round reset — skip to the next round or restart only the current round at any time, regardless of timer state
• Session recording — every completed round is written to SQLite with type, duration, and completion status

Statistics

• Dedicated stats window with three tabs:
  • Today — work and break round counts, total focus time, hourly breakdown chart
  • This Week — daily bar chart for the past seven days, current consecutive-day streak
  • All Time — 52-week heatmap (GitHub-style contribution calendar), lifetime session totals
• Charts use pure SVG; no external charting library
• Chart and heatmap colours are derived from the active theme
• Stats update live when a round completes — no manual refresh needed

Themes & Appearance

• 37 bundled themes including Pomotroid (dark), Pomotroid Light, Dracula, Nord, Tokyo Night, Gruvbox, Solarized, GitHub, One Dark, Rose Piné (3 variants), Catppuccin (4 variants), Synthwave, Ayu, Everforest, Kanagawa, Monokai, Night Owl, and more
• Auto light / dark mode — follows the OS prefers-color-scheme preference automatically; separate theme pickers for light and dark
• Custom theme hot-reload — drop a JSON theme file into the user themes folder and it appears instantly without a restart
• Theme colours propagate throughout the full UI and into the tray icon arc

Localization

• 7 languages — English, Spanish, French, German, Japanese, Chinese (Simplified), and Portuguese
• Auto-detects OS language on first launch; can be overridden manually in Settings
• All UI strings, settings labels, and notification messages are translated
• Locale-aware date and time formatting throughout (Intl.DateTimeFormat, reactive to language changes)
• Built with Paraglide JS v2 — compile-time, type-safe, tree-shakable message functions

Audio

• Configurable alert cues for work rounds, short breaks, and long breaks
• Custom audio — replace any of the three alert cues with your own file via a file picker
• Tick sounds — independently toggleable for work and break rounds
• Volume control — global volume slider (0–100)
• All audio runs on a dedicated thread via rodio; playback is guaranteed even when the window is hidden to the tray

System Tray

• Dynamic tray icon — a progress arc rendered with tiny-skia sweeps clockwise from 12 o'clock, coloured by round type (work / short break / long break)
• Countdown mode — optional inverted arc that fills from full to empty instead of empty to full
• Pause indicator — two vertical bars drawn over the icon when the timer is paused
• Tray menu — Show and Exit actions; left-clicking the icon toggles window visibility
• Minimise to tray and close to tray are independently configurable

Global Shortcuts

• Four actions — toggle (start / pause / resume), reset, skip, restart round
• Platform defaults — Control+F1–F4 on Windows and Linux; Command+Shift+1–4 on macOS
• Fully rebindable in Settings; supports modifier combinations and function keys
• Shortcuts work when the window is hidden to the tray

macOS

• Global shortcuts via Accessibility — shortcuts use the macOS Accessibility API; a contextual notice in Settings guides through granting permission with a direct link to System Settings
• Native window style — overlay titlebar with macOS-native traffic-light controls
• Platform-aware defaults — tray settings hidden on macOS where they are not applicable; shortcut defaults use Command instead of Control

Desktop Notifications

• Native OS notifications on round completion via tauri-plugin-notification
• Linux uses notify-send (libnotify) to avoid D-Bus session bus conflicts
• Notifications include round type and duration

WebSocket Integration

• Opt-in local WebSocket server (default off) for stream overlays and external integrations
• Listens on ws://127.0.0.1:<port> (localhost only); default port 1314
• Broadcasts roundChange events with full timer state; clients can query current state with getState
• Port is configurable; enable / disable at runtime from Settings → Advanced

Diagnostics & Logging

• Rotating log file written to the OS log directory (5 MB max, keeps one backup)
• Structured log entries for all major events — timer state changes, settings loads, audio playback, shortcut registration, round completions
• Panics are captured to the log before the process terminates
• Verbose logging toggle in Settings → Advanced switches between INFO and DEBUG level
• Open Log Folder button in Settings → About for quick access

Settings

26 configurable values across seven sections — Timer, Appearance, Notifications, Audio, Shortcuts, Advanced, and About. All settings are persisted to SQLite and take effect immediately without a restart (except WebSocket port).

Breaking Changes

• Settings are no longer stored in user-preferences.json. All preferences reset to defaults on first launch after upgrading from v0.x.
• The minimum OS requirement follows Tauri 2 system minimums: Windows 10+, macOS 10.13+, Linux with GTK 3.24+.
• Custom theme JSON files from v0.x are fully compatible — no changes needed.
