* feat(v2): add runtime.ResetSignalHandlers() for Linux panic recovery
Add a new runtime function that allows users to reset signal handlers
before code that might panic from nil pointer dereferences.
On Linux, WebKit installs signal handlers without the SA_ONSTACK flag,
which prevents Go from properly recovering from panics caused by
SIGSEGV and other signals. This function adds SA_ONSTACK to the
relevant signal handlers (SIGSEGV, SIGBUS, SIGFPE, SIGABRT).
Usage:
```go
go func() {
defer func() {
if err := recover(); err != nil {
log.Printf("Recovered: %v", err)
}
}()
runtime.ResetSignalHandlers()
// Code that might panic...
}()
```
The function is a no-op on macOS and Windows.

* test(v2): add panic-recovery-test example
Add an example that demonstrates the Linux signal handler issue (#3965)
and verifies the fix using runtime.ResetSignalHandlers().
The example includes:
- A Greet function that triggers a nil pointer dereference after a delay
- Auto-call from frontend after 5 seconds
- README with reproduction steps

This fixes some long-standing inconsistencies between
dev mode builds and production builds but is a breaking
change. Dev mode uses custom scheme for Vite versions >= 3.0.0
and for older it still behaves in the old way.
