feat(cli): M-Tool 1-3 — CLI, templates, Gitea publishing pipeline

Phase B complete: Shade now has a full developer tooling story. @shade/cli - shade init with project scaffolding from templates - shade fingerprint (own or peer) - shade publish (re-upload bundle) - shade rotate (--identity for full rotation, otherwise signed prekey) - shade peer add/list/verify/remove - shade dashboard (opens observer in browser) - shade doctor (diagnose config, storage, prekey server reachability) - Config from .shaderc.json or SHADE_* env vars Templates (in packages/shade-cli/templates/) - bun-server — Bun + Hono backend with /send + /receive endpoints - chat-demo — Two-process Alice/Bob chat over HTTP Publishing pipeline (Gitea npm registry) - .gitea/workflows/test.yml — CI on push/PR with PostgreSQL service - .gitea/workflows/publish.yml — publish on git tag v* - scripts/publish-all.ts — local publish helper with DRY_RUN support - scripts/bump-version.ts — lockstep version bump across all packages - Root package.json scripts: version, publish:dry, publish:all Also: /health endpoint now lives in createPrekeyRoutes so doctor can probe it without needing the full standalone setup. Dry-run verified: all 11 packages pack cleanly. 246 tests passing, 0 failures. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

 ## Quick start
 Add the Gitea npm registry to your project's `.npmrc`:
 ```
@shade:registry=https://gt.zyon.no/api/packages/Stian/npm/
 ```
 Then install the SDK (one-liner for most use cases):
 ```bash
 bun add @shade/sdk
 ```
 Or install specific packages if you need fine-grained control:
 ```bash
 # In your project
 bun add @shade/core @shade/crypto-web @shade/storage-sqlite
 ```
 Even faster — scaffold a new project with the CLI:
 ```bash
 bun add -g @shade/cli
 shade init my-app --template bun-server
 cd my-app && bun install && bun run start
 ```
 Magic one-liner with the SDK:
 ```ts
 import { createShade } from '@shade/sdk';
 const shade = await createShade({
  prekeyServer: 'https://shade.example.com',
  storage: 'sqlite:/data/shade.db',
  address: 'alice@example.com',
 });
 // Send (auto-establishes session if none exists)
 const envelope = await shade.send('bob@example.com', 'Hello, encrypted world!');
 // Receive
 const plaintext = await shade.receive('alice@example.com', incomingEnvelope);
 // Your safety number for out-of-band verification
 console.log(await shade.fingerprint);
 ```
 Or use the lower-level packages directly if you need full control:
 ```ts
 import { ShadeSessionManager } from '@shade/core';
 import { SubtleCryptoProvider } from '@shade/crypto-web';
 import { SQLiteStorage } from '@shade/storage-sqlite';
-const crypto = new SubtleCryptoProvider();
+const manager = new ShadeSessionManager(
-const storage = new SQLiteStorage('/data/shade-client.db');
+  new SubtleCryptoProvider(),
-
+  new SQLiteStorage('/data/shade.db'),
-const manager = new ShadeSessionManager(crypto, storage);
+);
 await manager.initialize();
 // Establish a session with a peer (after fetching their bundle)
 await manager.initSessionFromBundle('bob', bobBundle);
 // Encrypt
 const envelope = await manager.encrypt('bob', 'Hello, encrypted world!');
 // Decrypt
 const plaintext = await manager.decrypt('alice', incomingEnvelope);
 ```

 ## Publishing
 All packages publish to a self-hosted Gitea npm registry on `gt.zyon.no`.
 ```bash
 # Bump all packages in lockstep
 bun run version 1.1.0
 # Dry-run (pack all tarballs without publishing)
 bun run publish:dry
 # Real publish (requires GITEA_TOKEN env var)
 bun run publish:all
 # Or via CI: push a git tag v1.1.0 and .gitea/workflows/publish.yml runs

 # __PROJECT_NAME__
 A Shade-enabled Bun + Hono server. Encrypted messages in/out via two HTTP endpoints.
 ## Prerequisites
 A running Shade prekey server. The default is `__PREKEY_SERVER__`. You can either:
 - Run one locally: `docker run -p 3900:3900 shade-prekey-server`
 - Override with `SHADE_PREKEY_SERVER=...` in `.env`
 ## Run
 ```bash
 bun install
 bun run start
 ```
 The server registers itself with the prekey server on startup.
 ## Endpoints
 ### Send an encrypted message
 ```bash
 curl -X POST http://localhost:3000/send \
  -H "Content-Type: application/json" \
  -d '{"to": "peer-name", "message": "hello"}'
 ```
 Returns a `ShadeEnvelope` you can forward to the peer via any transport.
 ### Receive an encrypted envelope
 ```bash
 curl -X POST http://localhost:3000/receive \
  -H "Content-Type: application/json" \
  -d '{"from": "peer-name", "envelope": {...}}'
 ```
 Returns the decrypted plaintext.
 ## Next steps
 - Wire a real delivery layer (WebSocket, HTTP push, etc.)
 - Run `shade dashboard` to watch live activity
 - Compare fingerprints with peers out-of-band before trusting sessions

 # __PROJECT_NAME__
 Two-process chat demo: Alice and Bob talk via the Shade SDK over a simple
 HTTP relay. Shows how easy it is to add E2EE to any transport.
 ## Run
 Start a prekey server first (e.g. `docker run -p 3900:3900 shade-prekey-server`).
 Then in two terminals:
 ```bash
 bun run bob     # starts Bob's process on :4001
 bun run alice   # starts Alice's process on :4000
 ```
 Alice will send a message to Bob; both will print the activity.
