Setup repo: migrate architecture specs, code stubs, and tasks from alkhub_ts

Copy architecture docs, ADRs, storage domain specs, research, reviews,
and 56 storage architecture tasks from the alkhub_ts monorepo. Adapt for
standalone @alkdev/hub repo structure (src/ not packages/hub/).

Sanitize all sensitive information:
- Replace private IPs (10.0.0.1) with localhost defaults
- Remove internal server hostnames (dev1, ns528096)
- Replace /workspace/ private paths with npm package references
- Remove hardcoded credentials from examples
- Rewrite infrastructure.md without private network details

Add Deno project scaffolding: deno.json (pinned deps), .gitignore,
AGENTS.md, entry point. Migrate existing code stubs (crypto, config
types, logger) with updated import paths.

+## Description
+
+W14: Three terminology inconsistencies across ADRs and docs:
+- ADR-009 says "organization_members (membership with **roles**)" — contradicts ADR-012's rename to `membershipLevel`
+- ADR-012:55 uses `accounts.role: "service"` in rationale, despite mandating the rename to `accessLevel`
+- `agent-roles.md` also uses `accounts.role: "service"`
+
+Update ADR-009 to say "membership with levels." Update ADR-012:55 and agent-roles.md to use `accounts.accessLevel: "service"`.
+
+## Acceptance Criteria
+
+- [ ] ADR-009 updated: "membership with levels" instead of "membership with roles"
+- [ ] ADR-012:55 updated: `accounts.accessLevel: "service"` instead of `accounts.role: "service"`
+- [ ] `agent-roles.md` updated: `accounts.accessLevel: "service"` instead of `accounts.role: "service"`
+- [ ] No remaining references to the old terminology (`accounts.role`, `membershipLevel` as "roles")
