Summary

This change fixes VLESS share-link transport normalization in the converter.

• keep omitted headerType on plain tcp
• map type=tcp&headerType=http to network=http with http-opts
• map type=http to network=h2 with h2-opts
• add regression coverage for all three cases

Root Cause

The share-link parser mixed transport normalization with option generation.

That caused two problems:

• plain tcp links with no headerType could still synthesize default http-opts
• transport aliases were not normalized consistently, so HTTP camouflage and HTTP/2 handling were not mapped to the correct option blocks

Validation

• go test ./common/convert -run 'TestConvertsV2RayVless' -count=1
