Agent names derived from cwd using parent:prefix format:
- /home/user/src/ollie -> src:ollie
- /home/user/proj/ABC-123_feature/repo -> abc-123:repo
Updates:
- Kate plugin: one agent per project, git root fallback if no project plugin
- acme-ollie-ensure: single 'acme' session, per-project agents
- ollie-session-here: single 'default' session, per-project agents
Also fixed write -> rdwr for session/agent creation endpoints
Drop the OLLIE_KF5 CMake option and the entire Qt5/KF5 build branch;
delete KF5-only assets (99-ollie-kf5.sh, ollie-actions-kf5.desktop);
collapse all QT_VERSION_MAJOR and KTEXTEDITOR_VERSION_MAJOR conditionals
to the KF6 path in the KRunner, Kate, KIO, and GUI sources; update
Makefile, README, and docs. Verified: KF6 configure + full build of
ollie-gui, krunner_ollie, ollie_kate, kio_ollie.
