discoverDroidModels ran `droid models`/`droid model list`, which aren't real
droid commands — they parse as a prompt and launch a persistent
`droid exec --stream-jsonrpc` agent session that never exits, leaking a process
per call. The dashboard reloads the droid extension on every chat-send, so these
piled into dozens of orphaned `droid` processes.
Switch discovery to parse `droid exec --help` (lists Available + Custom models,
exits cleanly) via new parseDroidModelsFromHelp, and add a SIGKILL-on-timeout
guard so a wedged spawn can never leak. Verified against the real binary: 46
models, 0 leaked processes.

The merge delivers a new `fusion-plugin-droid-runtime` plugin providing a full MCP server and runtime adapter for droid-based agents, with event bridging, process management, tool mapping, and a prompt builder. It also adds agent delegation and org hierarchy tools to the pi extension, while fixing a
