How-to: run without containers

runner.kind = "shell" + cmd (alias: "script") — the watcher still does webhook verification, the queue, detached worktrees and statuses; your script does the build. No dagger, no docker, no image pulls.

[runner]
kind = "shell"
cmd = "./ci.sh" # run with `bash -c` in the worktree

The worktree is a detached checkout of the pushed sha at <worktree.base>-<repo>-<sha12>, removed after the run. A killed run reports "cancelled (superseded)", not failure.

Use it for: make ci, ./ci.sh, a linter gate, or bupha's own scripts/release.sh (debounced release job). For anything heavier — cache volumes, toolchains, parallel shards — use the dagger runner and the shared modules/dagger module.
