Move Tractor's project-specific test knowledge into the local harness

Deats,
- document current Python envs, pytest opts, backends, and transports.
- replace broad registry and process cleanup rules with scoped checks.
- record capture, diagnostics, reaper, and expected-outcome caveats.
- ignore canonical Claude and OpenCode links plus Taken runtime state.
(this patch was generated in some part by `opencode` using
`gpt-5.6-sol` (`openai`))
