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.

+name: Add Spoke 'reconnecting' Status or Document DB-Free Approach
+status: completed
+depends_on: []
+scope: narrow
+risk: low

+
+## Description
+
+W06: The spoke status enum is only `connected`/`disconnected`. The spoke-runner.md describes a reconnection flow, but there's no `reconnecting` state. A spoke with a dropped WebSocket shows `disconnected`, indistinguishable from a permanently offline spoke.
+
+Either add `reconnecting` to the spoke status enum, or document that reconnection is handled at the application layer (WebSocket reconnect timer) without a DB state change.
+
+## Acceptance Criteria
+
+- [ ] Either `reconnecting` added to `spokes.status` enum in `spokes.md` and `table-reference.md`, OR
+- [ ] Document explicitly that reconnection is application-layer-only (no DB state change) with rationale
+- [ ] `spoke-runner.md` reconnection flow section references the decision
