Implement roadmap items across booter, protocol, kernel bundle, coreutils, and docs.

- Hyperswarm connection caps (env + /proc + disk.os replication_operator_sketch)
- Protomux operator metrics schema; warm-cache invalidation on replication
- ctx.bareOsSyscall nanosleep; socket bridge getsockopt/setsockopt (keepalive/nodelay)
- Extension signer pin verification before kernel.ext.d scripts; ctx/DTS updates
- Structured seeder logging (BARE_OS_SEED_LOG_*); release-checklist holepunch drift
- POSIX profile/matrix/conformance lists + handbook/env appendix/kernel-extensions
- Coreutils printf golden tests; sync kernel ↔ seeder parity after bundle
