Subject: [PATCH 1/5] refactor: centralize WhatsApp version to single source of
 truth
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Instead of maintaining the version number in 3 separate files
(baileys-version.json, index.ts, generics.ts), this change makes
baileys-version.json the single source of truth. Other files now
import the version from this JSON file.

This follows the DRY principle and reduces:
- Risk of version inconsistency across files
- Maintenance burden (only 1 file to update)
- PR diff size (3 files → 1 file for version updates)
- Merge conflict probability

Addresses inefficiency found in Baileys PR #2269.

Subject: [PATCH 2/5] feat: improve version update robustness and frequency
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Changes:
- Update frequency: weekly → daily (06:00 UTC)
- Add retry with exponential backoff (3 attempts per source)
- Add multiple source endpoints (sw.js + bootstrap page)
- Add version validation (sanity checks on revision numbers)
- Add fetch timeout to prevent hanging
- Add detailed logging for debugging
- Simplify workflow to only update baileys-version.json

This makes the version update more reliable and responsive
to WhatsApp Web changes.

Subject: [PATCH 3/5] feat: add makeWASocketAutoVersion for automatic version
 fetching

Adds a new async function that automatically fetches the latest
WhatsApp Web version from web.whatsapp.com before connecting.

Usage:
```typescript
// Option 1: Auto-fetch version (recommended)
const sock = await makeWASocketAutoVersion({ auth: state })

// Option 2: Manual version (existing behavior)
const sock = makeWASocket({ auth: state })
```

Benefits:
- No need to update library for version changes
- Automatic fallback to bundled version if fetch fails
- Logged warnings when using fallback

Subject: [PATCH 4/5] feat: add periodic version check with soft reconnection

Implements automatic version updates that are transparent to users:

- Checks for new WhatsApp Web version every 6 hours (configurable)
- When new version detected, saves it for next natural reconnection
- Emits 'version.update' event so users can track updates
- No disconnection required - WhatsApp naturally reconnects every 30min-2h
- Cleans up interval when socket closes

Configuration:
```typescript
const sock = await makeWASocketAutoVersion({
    auth: state,
    versionCheckIntervalMs: 6 * 60 * 60 * 1000 // 6 hours (default)
})

sock.ev.on('version.update', ({ currentVersion, newVersion, isCritical }) => {
    console.log(`New version: ${newVersion.join('.')}`)
})
```

Subject: [PATCH 5/5] fix: address PR review comments

Fixes from code review:

1. Fix #1,6: Use connection.update event instead of overriding sock.end()
   - Listens for 'close' event to cleanup interval
   - Handles both explicit close and internal disconnections

2. Fix #3: Exit code 2 when fetch fails (not 0)
   - Allows CI to distinguish success/error/fetch-failed
   - Properly signals fetch failures to workflows

3. Fix #4: Document revision bounds + add env vars
   - Added detailed comments explaining min/max revision values
   - Made configurable via WA_MIN_REVISION/WA_MAX_REVISION env vars

4. Fix #5,9: Remove unused fetchLatestVersion option
   - Removed from SocketConfig and defaults
   - Updated versionCheckIntervalMs docs to clarify it's only for makeWASocketAutoVersion

5. Fix #7: Use separate variable for version tracking
   - trackedVersion instead of mutating mergedConfig
   - Prevents unexpected side effects

6. Fix #8: Check socket state before emitting events
   - isSocketClosed flag to prevent race conditions
   - Double-check after async operations

7. Fix #10: Implement force parameter in workflow
   - Creates PR even without version changes when force=true
   - Useful for re-triggering updates manually

Note: Test coverage (Fix #2) deferred to separate PR due to
ESM mocking complexity with Jest.

+ * These bounds can be overridden via environment variables if WhatsApp changes their
