Align the booter and docs with the kernel POSIX and stack-hardening roadmap: refresh

vendored Bare bundles and seeder parity; tighten the no-`node:` verifier and host-vs-image
docs; expand syscall/proc JSON with POSIX XSH-style ops, errno hints, signals, and schema
updates; add simulated FD table hooks, pathconf/getconf coverage, IPC message-queue surface,
swarm/protomux pool metrics and HyperDHT stats env; extend systemctl verbs, cron TZ-aware
matching, Pear updater and corestore snapshot hints, WASM instantiate behind a gate, and
runBin default timeout merging with caller abort options.

Bump BARE_OS_CTX_API_VERSION to 1.34.0 and BARE_OS_POSIX_PROFILE_VERSION to 1.0.1; sync
declared profile, compliance matrix, handbook, example syscalls JSON, CHANGELOG, and
generated ctx client helper; extend bare-os-ctx.d.ts for new ctx members.
