fix(ui): improve pressure monitor visibility and add timeline synchronization

SUMMARY:
Fixed button visibility issues in Context Pressure Monitor and added
interactive timeline synchronization. Three selectable execution paths
with realistic timing profiles.

UI FIXES (pressure-chart.js):
- Reduced gauge size 20% to prevent arc cut-off
- Changed button layout to side-by-side (flex-row)
- Fixed Reset button contrast (bg-gray-900 for WCAG AA)
- Added mobile responsive layout (flex-col sm:flex-row)
- Removed all wrapper div backgrounds causing visibility issues
- Trigger timeline simulation when pressure simulation runs

TIMELINE ENHANCEMENTS (activity-timeline.js):
- Added three execution path profiles (Fast/Standard/Complex)
- Fast: 65ms total (simple requests, all checks pass)
- Standard: 135ms total (needs validation and verification)
- Complex: 285ms total (requires deliberation and consensus)
- Real-time event activation synchronized with pressure changes
- Added timing disclaimer (estimates based on performance data)
- Path selection UI with radio buttons

ARCHITECTURE PAGE:
- Updated script versions for cache-busting
- Added test page for standalone pressure chart debugging

ISSUE RESOLVED:
User reported 'Simulate Pressure Increase' button hidden. Root cause:
Tailwind CSS class conflicts (user correctly identified early). Resolved
by simplifying button layout and removing constraining containers.
