* docs: add a Commands reference to the README
The commands were only mentioned scattered through prose, and two install
blurbs had gone stale (OpenCode omitted /ponytail-debt, Gemini omitted audit
and debt). Add one canonical Commands table (all five commands + what each
does + which hosts support them) and point the install blurbs at it so they
stop drifting as commands are added.

* docs: add pi to the portability table, de-stale the Gemini row
pi was a supported integration (pi-extension, README install, registers all
the commands) but had no row in the Supported Adapters table. The Gemini row
also enumerated an outdated command list; point it at commands/*.toml
generically so it stops drifting.
