fix(multi-cli): complete solution details display in summary tab (#98)

Fixed issue where multi-CLI planning solution cards only showed count,
feasibility, effort, and risk badges but had empty content area.

Changes:
- Enhanced renderMultiCliSummaryContent() to extract and display all solution fields
  - Solution name (name/title)
  - Feasibility score (feasibility)
  - Effort level (effort)
  - Risk level (risk)
  - Summary/description (summary)
  - Pros list (pros)
  - Cons list (cons)

- Added CSS styles for solution cards
  - .solution-details, .details-label, .details-list
  - .solution-header, .solution-title-row, .solution-badges
  - .badge with variants for feasibility/effort/risk

- Fixed related issues:
  - Added multiCliPlan support to backend data structures
  - Exposed liteTaskDataStore to window for global access
  - Fixed header left-alignment in detail pages
  - Added 'active' class to tab content for visibility
