bcde8b733c docs: update mesh-protocol-gaps with actual measurements
Key findings from actual benchmarks:
- MLS KeyPackage: 306 bytes (6 LoRa fragments, ~4 sec)
- MLS Welcome: 840 bytes (17 fragments, ~10 sec)
- MLS-Lite: 129 bytes without sig, 262 with sig
- MeshEnvelope V2: 336 bytes (~18% savings over V1)

Classical MLS is LoRa-viable! Group setup takes ~14 sec at 1% duty.
Post-quantum hybrid (2.6KB KeyPackage) is still impractical.

Updated action items to reflect completed work:
- MLS-Lite implemented
- MeshEnvelope V2 implemented
- Size measurements complete

01bc2a4273 docs: add mesh protocol gap analysis and MLS-Lite design
Honest assessment of QuicProChat vs Reticulum/Meshtastic/Briar:
- MLS overhead (500-800 byte KeyPackages) impractical for SF12 LoRa
- KeyPackage distribution over mesh unsolved
- No lightweight mode for constrained links

MLS-Lite design proposes 41-byte overhead symmetric mode:
- ChaCha20-Poly1305 with HKDF key derivation
- Optional Ed25519 signatures
- Upgrade path to full MLS when faster transport available
- QR code / out-of-band key exchange
