feat(statusline): add total AI agent time to CC statusline display

Display totalSessionSeconds from backend GraphQL API in the statusline.
The new display format shows agent time in magenta between daily cost
and context percentage:

🤖 model | 💰 $session | 📊 $daily | ⏱️ time | 📈 context%

Time is formatted as:
- Under 1 minute: 45s
- Under 1 hour: 2m5s
- 1+ hours: 1h30m (drops seconds for readability)

Changes:
- Add TotalSessionSeconds to GraphQL query and response types
- Update daemon CCInfoCache and CCInfoResponse structs
- Add CCStatuslineDailyStats type for cache and service layer
- Add formatSessionDuration helper function
- Update all related tests
