Track exact StarletOS bootstrap integration and checkpoint provenance

Recover 16 modified and 6 previously untracked integration files. All 22 source SHA-256s match the pre-publication StarletOS snapshot. Add handoff instructions, byte-preserving attributes and private backup exclusion. This commit publishes existing behavior; it does not claim a new full build or hardware qualification. The two preceding local commits and staged files were screened before publication.
