sentry-panic: switch to PanicHookInfo from deprecated PanicInfo

[mvanhorn]

Closes #862.

The workspace MSRV is 1.88 (Cargo.toml), so std::panic::PanicHookInfo (stabilized in 1.81) is always available. This removes the six #[allow(deprecated)] annotations that were silencing the PanicInfo deprecation warning and uses PanicHookInfo directly in sentry-panic.

Source compatibility

std keeps PanicInfo as a type alias for PanicHookInfo:

// library/std/src/panic.rs
pub type PanicInfo<'a> = PanicHookInfo<'a>;

So downstream extractor closures that still use &PanicInfo<'_> continue to match the new &PanicHookInfo<'_> signatures on add_extractor, event_from_panic_info, and message_from_panic_info.

Scope

Only sentry-panic/src/lib.rs is touched. No other crates reference PanicInfo.

Verified with cargo build --all, cargo clippy -p sentry-panic, cargo fmt -p sentry-panic --check, and cargo test -p sentry-panic.

Sorry about the bot @mvanhorn, this PR indeed looks valid. I'll review when I have time.

In general, we like issues to be opened before PRs, but for simple stuff like this change, I think the issue is not necessarily needed.

Thanks again for your contribution!

Ok, just did a quick review; I am not sure whether we should do this at all, since it would break our public API.

Unless using PanicInfo is causing you some inconvenience, I would suggest we just keep the code as it is for now. Otherwise, perhaps it makes sense to open an issue to discuss the right approach after all 😅

If using PanicInfo is causing trouble for you, please open an issue to explain what the concrete problem is, and we can discuss a potential solution there.

Thanks for the quick look @szokeasaurusrex. The PR body covers this but may have buried it - std defines pub type PanicInfo<'a> = PanicHookInfo<'a> (type alias, not a separate type), so downstream extractor closures using &PanicInfo<'_> continue to match the new &PanicHookInfo<'_> signatures on add_extractor / event_from_panic_info / message_from_panic_info. No break at the public-API boundary, just silences the six #[allow(deprecated)] annotations.

Happy to close if you'd still rather leave things as-is - the deprecation warning is cosmetic and the allow attrs aren't hurting anything. Just didn't want you to have to merge another six #[allow(deprecated)] reminders down the line.
