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
+
+All spec/ADR consistency fixes. This group eliminates contradictions between ADRs, table specs, and other architecture documents. Inconsistent terminology and conflicting claims cause implementors to make wrong assumptions, so all docs must agree before they are treated as authoritative.
+
+## Acceptance Criteria
+
+- [ ] All dependent tasks are completed
+- [ ] Cross-references between completed tasks are consistent
+- [ ] No remaining contradictions in the covered domain
