kate: reuse single agent, write cwd on project change 

Instead of one-agent-per-project-directory, reuse the first agent in
the kate session. When the project changes, write the new directory
to the agent's ctl file (cwd command). Simpler model — one kate
session, one agent, cwd follows the active project.
