Fix/66 dashboard schedule and electron vite

[altaskur]

Description

Goal

Fix the dashboard not reflecting the daily schedule configured in the Calendar, migrate the build system to electron-vite for better DX and cross-platform support, and improve home page card layout consistency.

Key Changes

• Fix getDayTarget to use daySchedule per-day minutes instead of dividing weeklyMinutes evenly (fixes [Bug]: Dashboard does not reflect updated daily schedule from Calendar configuration #66)
• Fix workDays parsing from JSON.parse() to .split(',') matching the stored format
• Migrate build system from Angular CLI + manual Electron to electron-vite
• Add cross-platform asset serving Vite plugin (dev middleware + build copy)
• Constrain card dimensions (134px height, 356px max-width) with text overflow ellipsis
• Add AI guidelines for project contributors (.agent/rules/ia-rules.md)

Type of Change

• 🐛 Bug fix (non-breaking change which fixes an issue)
• ✨ New feature (non-breaking change which adds functionality)
• 💥 Breaking change (fix or feature that would cause existing functionality to not work as expected)
• 📝 Documentation update
• 🎨 Style/UI changes
• ♻️ Refactoring (no functional changes)
• ⚡ Performance improvement
• ✅ Test updates

Testing

How Has This Been Tested?

• Unit tests
• Integration tests
• Manual testing
• Tested with SonarQube analysis

Test Steps

1. Open the Calendar and set a day (e.g., Monday) to 8h 30m in Work Schedule Configuration
2. Navigate to Home (Dashboard)
3. Verify the "Today" card shows 0m / 8h 30m — Remaining: 8h 30m instead of the old 0m / 8h
4. Toggle theme to light mode, close and reopen the app — verify theme persists
5. Check all cards have consistent height and long text truncates with ellipsis

Test Configuration

• Node version: 22.x
• npm version: 10.x
• Platform tested: Windows

UI Changes

Before

• Dashboard showed 0m / 8h even when a day was configured to 8h 30m
• Cards had inconsistent heights and long text overflowed

After

• Dashboard correctly reflects per-day schedule from Calendar configuration
• Cards have uniform 134px height with text-overflow ellipsis on long names

Additional Context

The electron-vite migration replaces the previous Angular CLI + manual Electron build setup with a unified electron-vite configuration. This simplifies the build pipeline and provides HMR for the renderer process in development. The index.html was moved to the project root following Vite conventions, and a custom Vite plugin handles cross-platform asset serving (translations, icons) both in dev and production builds.

Reviewer Notes

• The core bug fix for [Bug]: Dashboard does not reflect updated daily schedule from Calendar configuration #66 is in src/app/pages/open-home/open-home.ts — focus on getDayTarget, isWorkDay, and getWorkDaysCount methods
• The electron-vite config (electron.vite.config.ts) includes a custom plugin for serving assets — worth reviewing the middleware approach
