v1.96.4-ouihelp.1

Custom Ouihelp build of Tailscale v1.96.4.

Patch: Linux firewall marks moved away from 0x80000 to avoid Cilium identity mark collisions:

• fwmark mask: 0xf000
• subnet-route mark: 0x1000
• bypass mark: 0x2000

The GitHub release tag is v1.96.4-ouihelp.1, but the embedded Tailscale short version remains 1.96.4 for compatibility with Tailscale infrastructure.

Assets contain linux/amd64 and linux/arm64 and binaries.
