Adds experimental native protocol mode (WAM\x05) as alternative to
web protocol (WA\x06\x03). Configurable via BAILEYS_PROTOCOL env var:
- web (default): standard WhatsApp Web protocol
- native: Android native protocol (may enable view-once media on companions)
When native mode is enabled:
- NOISE_WA_HEADER changes from WA\x06\x03 to WAM\x05
- DICT_VERSION changes from 3 to 5
- WebInfo is omitted from ClientPayload

Add webdPayload to WebInfo during connection with:
- supportsE2EImage/Video/Audio/Document = true
- supportsMediaRetry = true
- features bitmask with view-once capability flag
This may enable the WA server to deliver view-once media content
to Baileys companions instead of just <unavailable> placeholders.

When receiving <unavailable type='view_once'/>, attempt to request
the actual media content from the primary phone via PDO
(Peer Data Operation / PLACEHOLDER_MESSAGE_RESEND).
If the phone responds, the full media (url, mediaKey, directPath)
arrives via messages.upsert, allowing consumers to display the image.
Falls back to placeholder if PDO fails or phone doesn't respond.

The early unavailable handler at line ~2261 was intercepting
view_once stanzas and silently discarding them (sendMessageAck + return)
before the view_once_unavailable_fanout handler could emit them.
Now emits a viewOnceMessage placeholder with isViewOnce=true so
consumers receive the event in messages.upsert.

Two issues found during view-once testing on linked devices:
1. msmsg block removal:
The "temporary fix" that discarded all msmsg-type encrypted messages
was also blocking legitimate view-once messages. On linked devices,
view-once arrives as msmsg encryption type. The block was originally
added to prevent crashes from missing messageSecret, but the existing
try/catch in the decrypt path already handles those errors gracefully
by marking the message as a CIPHERTEXT stub.
2. view_once_unavailable_fanout emission:
When a linked device receives a view-once, the WA server sends only
<unavailable type="view_once"/> (no <enc> with actual media content).
Previously this was silently acknowledged without emitting any event,
so consumers (zpro, astra-api, etc.) never knew a view-once arrived.
Now it emits the message as a CIPHERTEXT stub with key.isViewOnce=true
so consumers can display "view-once message received" in their UI.
