feat(booter): cache syscalls proc JSON, net tuning hints, /dev/shm unlink, POSIX/docs sync
- Cache /proc/bare_os/syscalls.json until warm read cache clear; invalidate with vfs.bareOsClearWarmReadCaches
- net_summary: optional udxTuning / hyperswarmTuning from BARE_OS_UDX_* / BARE_OS_HYPERSWARM_* JSON
- Metric: operator.corestore_snapshot_hint on bareOsCorestoreSnapshotHint
- pathconf: _PC_NAME_MAX 128 under /dev/shm
- vfs: fix unlink for /dev/shm segments; add roundtrip test
- protocol: bareOsIsAllowedSeedRpcMethodShort + tests
- getconf: _POSIX_SHARED_MEMORY_OBJECTS, _POSIX_MESSAGE_PASSING, _POSIX_ASYNCHRONOUS_IO + test
- microbench: syscall suite (syscalls proc JSON stringify)
- JSON Schema bare-os-syscalls.schema.json schemaVersion 5; posix-conformance-matrix ops = getconf
- Docs: blind-relay security note, compat matrix (1.38.0 / 1.0.4), handbook 04/09, appendix, OTA note
- Pear: document host coupling in compatibility-matrix (no pear-runtime manifest entry)
