New

• Redesigned the daily and weekly work summary cards.
• Added color-coded daily segments to the weekly progress ring.
• Added an animated Monday-Friday breakdown with colored duration bars when the weekly
  card is clicked.
• Added a configurable daily target and check-in/check-out planning for today and
  tomorrow.
• Friday planning now uses the remaining weekly target automatically.
• Simplified weekly and monthly totals.
• Fixed calculations around day changes, completed sessions, leave-adjusted weekly
  targets, and exit times.
• Improved popup sizing, overflow behavior, time input, and animations.

v1.5.0 Release Notes:

• Moved from an in-page overlay panel to a browser-action popup — click the toolbar icon to open your summary, no page injection required
• Added daily snapshot caching: the extension parses ARGEPORTAL once a day and recomputes "today" and week totals from the cached data + current time, so the popup works instantly even with the portal tab closed
• Redesigned the dashboard with new progress rings for Today and This Week, an estimated exit time card, and clearer alternative weekly targets (36/27/18h)
• Added a staleness indicator when cached data isn't from today, prompting a refresh from ARGEPORTAL

Add a toggle button to the WeekNav header that switches between two
daily hour calculation modes:
- Sessions (default): sums portal's Çalışma Süresi per session
- First→Last: reads raw G/C entries from tableOne and computes
last exit minus first entry per day, correctly handling multiple
check-in/out pairs that the portal summary misses

Mode persists across sessions via localStorage.
