fix: com.apple.application-identifier needs a period

[janl]

There are two issues:

1. the value for the application-identifier entitlement is missing a period
2. the oro binary is not signed with the entitlements file

after applying the PR, run:

# rebuild
cargo build

# sign with entitlements
codesign -s - -f --entitlements crates/alabaster/src/macos/alabaster-swift/Sources/alabaster-swift/AlabasterSwift.entitlements target/debug/oro
target/debug/oro: replacing existing signature

# validate signature
codesign -d --entitlements - --xml target/debug/oro
Executable=/Users/jan/Work/rust/orogene/target/debug/oro
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "https://www.apple.com/DTDs/PropertyList-1.0.dtd"><plist version="1.0"><dict><key>com.apple.application-identifier</key><string>$(AppIdentifierPrefix).$(PRODUCT_BUNDLE_IDENTIFIER)</string><key>com.apple.security.app-sandbox</key><true/><key>com.apple.security.application-groups</key><array></array></dict></plist>

# now
> ./target/debug/oro mount
Trace/BPT trap: 5

note that cargo run mount will re-build and re-sign the binary to before our change, so this should really be part of the build process.

Now the new error is also not great, but a step forward.

• This could be some more MacOS weirdness, but e.g. none of the remediations https://apple.stackexchange.com/questions/113379/how-to-debug-trace-bpt-trap-5 helped
• this could be still bad code signing, I have not found a pointer to this yet
• this could be a genuine issue in the rust, swift or bridge code (c.f. https://developer.apple.com/forums/thread/705740)

Where does PRODUCT_BUNDLE_IDENTIFIER come from??

Normally from an app’s Info.plist. I’m not 100% sure how this works for not-really-apps. I’ll do some digging.
