v0.10.0 - Spatial Layout Visualization

What's New

session_map Visual Layout

The session_map tool now shows the actual spatial arrangement of panes within each tab:

╔══════════════════════════════════════════════════════════════╗
║ ● fascinating-quasar                                         ║
╚══════════════════════════════════════════════════════════════╝
    [Tab #1] idle
  ┌────────────────────────────┐┌─────────────┐┌─────────────┐
  │                            ││    shell    ││             │
  │          claude            │├─────────────┤│    shell    │
  │                            ││    shell    ││             │
  └────────────────────────────┘└─────────────┘└─────────────┘

• Shows side-by-side splits, stacked panes, and nested layouts
• Focused panes highlighted in orange
• Proportional sizing based on actual layout percentages
• Properly skips UI chrome (tab-bar, status-bar plugins)

Bug Fixes

• Fixed layout parser to handle nested pane structures
• Fixed plugin pane filtering (no more phantom shells)
• Improved T-junction rendering for overlapping borders
