Follow up perf interop: dotnet TLS and dialer stability

[acul71]

Context

The perf migration branch improved build/toolchain alignment and startup robustness for Go/JS/dotnet images, but a subset of interop cases still fail.

Remaining failure focus

• js-v3.x -> dotnet-v1.0 (tcp, tls, yamux) fails TLS negotiation (could not negotiate /tls/1.0.0).
• Some dotnet-v1.0 dialer paths can stall after earlier failures.

Why this issue

Track follow-up interoperability work separately from the migration stabilization changes already landed in all-stars-perf-migration.

Next steps

• Validate dotnet security protocol registration/selection against libp2p JS TLS expectations.
• Re-run focused matrix on dotnet listener/dialer permutations.
• Confirm full matrix behavior after targeted fixes.
