When testbox config is present, tool execution follows a two-phase
model tied to the existing plan/build agent architecture. The plan
agent continues to run locally for read-only exploration, while the
build agent requires a `testbox` parameter on every tool call
(read, write, edit, bash, glob, grep, list), routing execution to
an SSH-accessible CI runner with the repo's full environment.
A new `testbox/` module handles resolution and transport. The
`Testbox.resolve()` function calls an external API to map a testbox
name to SSH connection details, caching results with a TTL. The
`SSH` transport layer uses ControlMaster multiplexing and provides
primitives (exec, readFile, writeFile, glob, grep, list) that each
tool delegates to when a connection is present.
