feat(booter): POSIX/P2P roadmap — ctx 1.41.0, hrpc audit, warm-cache, Pear proc

- Bump BARE_OS_CTX_API_VERSION to 1.41.0; align syscalls.example, compat matrix,
  POSIX dashboard, and doc-contract verifier
- Stock hrpc: BARE_OS_HRPC_AUDIT chain rows; BARE_OS_HRPC_EMIT_UNLISTED for
  bare-os:hrpc-request; document seed/hrpc boundaries in KERNEL_CONTRACT +
  protocol CHANGELOG
- VFS: bareOsEvictWarmReadPrefixes; BARE_OS_VFS_WARM_CACHE_PREFIX_INVALIDATE +
  replicationLive schema 2; warm cache stats schema 2; hyperblobs gate metrics +
  failed-write counter
- maybeMergeBareFromDrive: BARE_OS_BARE_STDLIB_RESOLVE_CONCURRENCY (parallel reads,
  manifest order preserved)
- Word-7 proc: pear_runtime_channel.json + vfs maps/tests; host env passthrough
- Coreutils: export bareAwkRun for tests; build strips export in shipped awk;
  nextfile smoke test; getconf _SC_PAGESIZE test; man/hawk handbook tweaks
- Security/docs: vault AEAD tamper test in test.identity.js; vault threat model +
  users-manual; scripts/verify-doc-contracts.mjs in pretest
- Fix /proc readdir golden list order for new proc node; sync seeder kernel

kernel/lib/init/init-main.js
