Workspace Search and Replace

Perform a codebase-wide search and replace with intelligence:

Find: {{search_pattern}}
Replace with: {{replacement_pattern}}
Scope: {{file_glob_pattern}}

But this isn't a simple find-replace. For each occurrence:

1. **Read the surrounding context** (10 lines before and after)
2. **Classify** the usage:
   - Direct usage: Replace straightforwardly
   - Aliased: Update the alias/import too
   - Inside a string/comment: May need different handling
   - In a test: Update test expectations to match
   - In a type definition: Update the type and all references
3. **Apply the appropriate replacement** for each category
4. **Update imports** if the replacement changes the import source
5. **Check for TypeScript errors** after the replacement

Provide a summary:
- Total occurrences found: X
- Replaced: Y
- Skipped (with reason): Z
- Files modified: (list)
- New TypeScript errors introduced: (list with fixes)

If any replacement is ambiguous, show the context and ask rather than guessing.
