kate: add Ollie context menu to project tree view

Right-click on files/directories in Kate's project panel now shows
Ollie actions:

For directories:
- Ask about directory (explain purpose/structure)
- Start Session Here

For files:
- Ask about file (explain purpose/design)
- Review file (code review)
- Write tests

Constructs file paths by walking up the tree model and joining with
the project base directory.
