Handle FuncExact variant added in wasmparser 0.243.0

[Copilot]

wasmparser 0.243.0 adds FuncExact variant to ExternalKind and TypeRef enums for the custom descriptors feature, causing exhaustive match failures.

Changes

• Added panic handlers for ExternalKind::FuncExact and TypeRef::FuncExact in src/hyperlight_component_util/src/elaborate.rs
• Follows existing pattern for unsupported features (e.g., Tag)

ExternalKind::FuncExact => panic!("core type exact functions are not supported"),
// ...
TypeRef::FuncExact(_) => panic!("core type exact functions are not supported"),

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com//advisories
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
