feat(kernel): Wave 6 mega-phase — bits6, protocol, booter, docs, CI

- Add sixth capability word (bits6), STOCK_V6, FEATURE6_* in bare-os-protocol;
  seed caps, channel.js, seed-rpc-methods registry, replication/handshake fields
- Booter: Wave 6 /proc JSON surfaces, ctx 1.15.0, Pear/DHT hooks, subprocess
  snapshot v3, audit v3, extension registry v3 edges, hrpc stub, worker/sandbox
- Kernel: boot.policy v6 enforcement (requireFeatureBits6, booter semver, ctx min,
  extension deny/hash pins, offline LKG strict); example policy + seeder kernel sync
- Schemas: boot.policy v6, OTel JSONL v3 + example; validate-example-schemas pairs
- CI: verify-kernel-roadmap-wave6 (100 rows), verify-pear-no-static-node-import,
  extend wave3/compat-matrix/ctx verifiers; pretest wiring
- Docs: ADR 001 v6, kernel-capabilities-index Word 6, kernel-extensions,
  feature-roadmap Wave 6 table, compatibility matrix, handbook ch.11, developer-guide
  (privacy, bare-boot alignment, bare-fetch), http-curl, scripts/README, DOCUMENTATION
