Reorganize the source checkout layout

Browse source 
Separate tracked source from generated artifacts so the repo root stops accumulating helper scripts, manifests, and local runtime outputs.

Move manual shell entrypoints under scripts/, manifests under config/, and the Firecracker API reference under docs/reference/. Make build and runtimebundle now target build/bin, build/runtime, and build/dist as the canonical source-checkout paths.

Update runtime discovery, helper scripts, tests, and docs to follow the new layout while keeping legacy source-checkout runtime fallbacks for existing local bundles during migration.

Validated with bash -n on the moved scripts, make build, and GOCACHE=/tmp/banger-gocache go test ./....
