Fix Map tab showing no read/written files on Windows

Problem

On Windows, the Map tab always shows READ 0 / WRITTEN 0 and only renders the top-level folders, even when the session contains Read/Write/Edit steps. The root node also displays the full path (c:\Users\...\project) instead of just the folder name.

Cause

MapTab.tsx decides whether a file belongs to the project with:

if (fp.startsWith(cwdNorm + '/'))

On Windows both cwd and file_path use backslashes (c:\Users\...), so this check never matches and every absolute path falls into the else { continue; } branch. All file events are dropped.

A second mismatch makes it worse: VS Code often reports the cwd with a lowercase drive letter (c:\) while tool calls use uppercase (C:\), so even with matching separators a plain string comparison fails.

The root node name and the cwd label use cwd.split('/'), which returns the whole path when there are no forward slashes.

Fix

• Normalise both cwd and file_path to forward slashes before comparing.
• Compare drive-letter paths case-insensitively (Windows paths are case-insensitive). The relative path keeps its original casing for display.
• Split cwd on /[\\/]/ for the root node name and the cwd label.

POSIX paths behave exactly as before.

Testing

• npm run compile, npm run build:webview and npm run lint pass (no new warnings).
• Checked the path logic against:
  • cwd c:\Users\Neko\...\project + file C:\Users\Neko\...\project\data\agents.json → data/agents.json
  • cwd c:\...\project + file c:/.../project/src/App.tsx → src/App.tsx
  • cwd /home/a/proj + file /home/a/proj/src/x.ts → src/x.ts (unchanged)
  • cwd /home/a/proj + file /etc/x → skipped (unchanged)
• Installed the packaged .vsix on Windows 11 with a Claude Code session started from the VS Code extension.

Notes

Other components extract file names with path.split('/').pop() (FlowTab, InsightsTab, GlobalSearch, DependencyGraph, sessionListViewProvider) and will show full Windows paths instead of file names. I kept this PR focused on the Map tab, but I'm happy to follow up with a shared path helper if you'd like.
