feat(booter): hrpc allowlist parser, snapshot hints parity, shell pipefix, safer mv staging
- Add bare-os-hrpc-allowlist.js; wire stock bareOsHrpcRequest + bareOsHrpcAllowlistProbe;
passthrough BARE_OS_HRPC_ALLOWLIST_JSON and operator env for snapshot/blind-relay/mirror/pear-doctor
- Merge BARE_OS_CORESTORE_SNAPSHOT_WORKFLOW_JSON into bareOsReadSnapshotHintsJson (match proc)
- Shell: pipefail runs all pipeline stages; aggregate first non-zero exit after assign prefixes
- mv: stage renames via vfs.resolveLogical so temp files stay in writable destination dir
- coreutils: POSIX-style split suffixes past zz; xargs doc for -P vs host subprocess
- identity-session: stable Error.code for no-account / passphrase failures
- Docs: KERNEL_CONTRACT, POSIX profile, handbook 5/7/9, kernel-extensions strict-boot table,
env appendix, developer-guide + scripts README, protocol/booter CHANGELOGs; hrpc allowlist schema
- Tests: hrpc allowlist, pear_doctor schema 2, split suffix, pipefail pipeline; fix PLACEHOLDER_BASELINE link
Pretest: refreshed kernel bins, man.json, posix dashboard, bundle health, seeder parity
