feat(sdk): add CLI tool and SDK libraries for developer tooling (Phase 4)

Add comprehensive developer tooling for Gitea integration:

CLI Tool (cmd/gitea-cli/):
- gitea-cli auth login/logout/status - Authentication management
- gitea-cli upload release-asset - Chunked upload with progress
- gitea-cli upload resume - Resume interrupted uploads
- gitea-cli upload list - List pending upload sessions
- Parallel chunk uploads with configurable workers
- SHA256 checksum verification
- Progress bar with speed and ETA display

Go SDK (sdk/go/):
- GiteaClient with token authentication
- User, Repository, Release, Attachment types
- ChunkedUpload with parallel workers
- Progress callbacks for upload tracking
- Functional options pattern (WithChunkSize, WithParallel, etc.)

Python SDK (sdk/python/):
- GiteaClient with requests-based HTTP
- Full type hints and dataclasses
- ThreadPoolExecutor for parallel uploads
- Resume capability for interrupted uploads
- Exception hierarchy (APIError, UploadError, etc.)

TypeScript SDK (sdk/typescript/):
- Full TypeScript types and interfaces
- Async/await API design
- Browser and Node.js compatible
- Web Crypto API for checksums
- ESM and CJS build outputs

All SDKs support:
- Chunked uploads for large files
- Parallel upload workers
- Progress tracking with callbacks
- Checksum verification
- Resume interrupted uploads

# Gitea Python SDK
Official Python SDK for the Gitea API with chunked upload support for large files.
## Installation
```bash
pip install gitea-sdk
```
## Quick Start
```python
from gitea import GiteaClient
# Create client
client = GiteaClient("https://gitea.example.com", token="your_token")
# Get current user
user = client.get_current_user()
print(f"Logged in as {user.login}")
# Get a repository
repo = client.get_repository("owner", "repo")
print(f"Repository: {repo.full_name}")
```
## Chunked Upload
Upload large files with progress tracking and resume capability:
```python
from gitea import GiteaClient
client = GiteaClient("https://gitea.example.com", token="your_token")
# Upload a release asset with progress callback
def on_progress(p):
print(f"\rProgress: {p.percent:.1f}% ({p.speed_formatted}) ETA: {p.eta}", end="")
with open("large-file.tar.gz", "rb") as f:
result = client.upload_release_asset(
owner="myorg",
repo="myrepo",
release_id=123,
file=f,
filename="large-file.tar.gz",
chunk_size=50 * 1024 * 1024, # 50MB chunks
parallel=4,
verify_checksum=True,
progress_callback=on_progress,
)
print(f"\nUploaded: {result.download_url}")
```
## Resume Interrupted Uploads
```python
# Resume an interrupted upload
result = client.resume_upload(
session_id="sess_abc123",
file=open("large-file.tar.gz", "rb"),
progress_callback=on_progress,
)
```
## API Reference
### GiteaClient
#### Constructor
```python
client = GiteaClient(
base_url="https://gitea.example.com",
token="your_api_token",
timeout=30, # Request timeout in seconds
)
```
#### User Methods
- `get_current_user()` - Get authenticated user
- `get_user(username)` - Get user by username
#### Repository Methods
- `get_repository(owner, repo)` - Get repository
- `list_user_repos(username)` - List user's repositories
#### Release Methods
- `get_release(owner, repo, release_id)` - Get release by ID
- `get_release_by_tag(owner, repo, tag)` - Get release by tag
- `list_releases(owner, repo)` - List all releases
#### Upload Methods
- `upload_release_asset(...)` - Upload release asset with chunked upload
- `resume_upload(session_id, file)` - Resume interrupted upload
- `get_upload_session(session_id)` - Get upload session status
- `cancel_upload(session_id)` - Cancel upload session
## Error Handling
```python
from gitea import GiteaClient, APIError, AuthenticationError, NotFoundError
client = GiteaClient("https://gitea.example.com", token="your_token")
try:
repo = client.get_repository("owner", "nonexistent")
except NotFoundError as e:
print(f"Repository not found: {e}")
except AuthenticationError as e:
print(f"Authentication failed: {e}")
except APIError as e:
print(f"API error [{e.code}]: {e.message}")
```

# Gitea TypeScript/JavaScript SDK
Official TypeScript/JavaScript SDK for the Gitea API with chunked upload support for large files.
## Installation
```bash
npm install @gitea/sdk
# or
yarn add @gitea/sdk
# or
pnpm add @gitea/sdk
```
## Quick Start
```typescript
import { GiteaClient } from '@gitea/sdk';
// Create client
const client = new GiteaClient({
baseUrl: 'https://gitea.example.com',
token: 'your_token'
});
// Get current user
const user = await client.getCurrentUser();
console.log(`Logged in as ${user.login}`);
// Get a repository
const repo = await client.getRepository('owner', 'repo');
console.log(`Repository: ${repo.full_name}`);
```
## Chunked Upload
Upload large files with progress tracking:
```typescript
import { GiteaClient } from '@gitea/sdk';
const client = new GiteaClient({
baseUrl: 'https://gitea.example.com',
token: 'your_token'
});
// Upload a release asset with progress
const file = new File([...], 'large-file.tar.gz');
const result = await client.uploadReleaseAsset({
owner: 'myorg',
repo: 'myrepo',
releaseId: 123,
file,
chunkSize: 50 * 1024 * 1024, // 50MB chunks
parallel: 4,
verifyChecksum: true,
onProgress: (p) => {
console.log(`Progress: ${p.percent.toFixed(1)}%`);
console.log(`Speed: ${formatBytes(p.speed)}/s`);
console.log(`ETA: ${formatDuration(p.eta)}`);
}
});
console.log(`Uploaded: ${result.browser_download_url}`);
```
## Using ChunkedUpload Directly
For more control over the upload process:
```typescript
import { GiteaClient, ChunkedUpload } from '@gitea/sdk';
const client = new GiteaClient({
baseUrl: 'https://gitea.example.com',
token: 'your_token'
});
const upload = client.createChunkedUpload('owner', 'repo', 123, {
chunkSize: 50 * 1024 * 1024,
parallel: 4,
onProgress: (p) => console.log(`${p.percent.toFixed(1)}%`)
});
try {
const result = await upload.upload(file, 'filename.tar.gz');
console.log(`Success: ${result.browser_download_url}`);
} catch (error) {
// Upload failed, can retry later
const session = upload.getSession();
console.log(`Resume with session: ${session?.id}`);
}
```
## API Reference
### GiteaClient
#### Constructor
```typescript
const client = new GiteaClient({
baseUrl: 'https://gitea.example.com',
token: 'your_api_token',
timeout: 30000, // Request timeout in milliseconds
});
```
#### User Methods
- `getCurrentUser()` - Get authenticated user
- `getUser(username)` - Get user by username
#### Repository Methods
- `getRepository(owner, repo)` - Get repository
- `listUserRepos(username)` - List user's repositories
#### Release Methods
- `getRelease(owner, repo, releaseId)` - Get release by ID
- `getReleaseByTag(owner, repo, tag)` - Get release by tag
- `listReleases(owner, repo)` - List all releases
#### Upload Methods
- `uploadReleaseAsset(options)` - Upload release asset with chunked upload
- `createChunkedUpload(owner, repo, releaseId, options)` - Create upload handler
- `getUploadSession(sessionId)` - Get upload session status
- `cancelUpload(sessionId)` - Cancel upload session
## Error Handling
```typescript
import {
GiteaClient,
APIError,
AuthenticationError,
NotFoundError,
UploadError
} from '@gitea/sdk';
const client = new GiteaClient({
baseUrl: 'https://gitea.example.com',
token: 'your_token'
});
try {
const repo = await client.getRepository('owner', 'nonexistent');
} catch (error) {
if (error instanceof NotFoundError) {
console.log(`Repository not found: ${error.message}`);
} else if (error instanceof AuthenticationError) {
console.log(`Authentication failed: ${error.message}`);
} else if (error instanceof UploadError) {
console.log(`Upload failed: ${error.message}`);
console.log(`Session: ${error.sessionId}, Chunk: ${error.chunk}`);
} else if (error instanceof APIError) {
console.log(`API error [${error.code}]: ${error.message}`);
}
}
```
## Browser Support
This SDK works in modern browsers that support:
- `fetch` API
- `crypto.subtle` for SHA-256 checksum
- `File` and `Blob` APIs
For Node.js, you may need to polyfill `fetch` for versions < 18.
