docs: sync documentation with codebase

What drifted

File	Drift	Fix
README.md	"47 event kinds" — schema.ts defines 48 (UnknownCommandWarn + IdeSocketAccessBlocked)	Updated to 48
README.md	agentguard deepagents-init in CLI reference — no command file or switch case exists	Removed
CLAUDE.md	Kernel loop step 4: "21 defaults" — source defines 24 invariants	Updated to 24
CLAUDE.md	commands/ directory comment listed deepagents-hook, deepagents-init (removed) and omitted goose-init (added)	Replaced
CLAUDE.md	policies/ comment omitted essentials pack (policies/essentials.yaml exists)	Added
CLAUDE.md	CLI Commands section documented deepagents-hook and deepagents-init — no source files exist	Removed, added goose-init

Verification

Each fix was verified against the actual source code:

• Event count: manually counted all export const ... EventKind declarations in packages/events/src/schema.ts (48)
• Invariant count: id: fields in packages/invariants/src/definitions.ts (24)
• Commands: switch (command) cases in apps/cli/src/bin.ts — no deepagents-hook/init case, goose-init case present
• Policy packs: ls policies/ — essentials.yaml present, others in subdirs
• Command files: apps/cli/src/commands/deepagents*.ts — no files; goose-init.ts — exists

Dogfood note

AgentGuard governance hook blocked writes initially because apps/cli/dist/bin.js was not built in the worktree. The bootstrap exemption (pnpm build pattern) correctly allowed self-bootstrapping. No governance issues encountered after kernel was built.

Superseded by #1320 which covers the same drift plus ARCHITECTURE.md and additional commands (codex-init, gemini-init, goose-init). Closing in favor of #1320 once #1353 (CI fix) lands and unblocks *.md PRs.
