Package Swift stdlibs with macOS CLI

[alokedesai]

Description

Adds Swift runtime sidecar packaging for the standalone macOS CLI/remote-server artifact:

• Adds CLI rpaths for /usr/lib/swift and @executable_path/lib, preferring system Swift libraries on modern macOS while preserving a sidecar fallback layout.
• Uses xcrun swift-stdlib-tool during script/macos/bundle --artifact cli to collect required libswift*.dylib files into bundle/osx/lib.
• Includes lib in the macOS CLI release tarball alongside the binary and resources.
• Updates install_remote_server.sh to safely install an extracted lib/ sidecar to $install_dir/lib without changing the installed binary path.
• Adds a focused installer regression test for the lib/ sidecar path.

Note: the originally requested remote base branch aloke/remote_code_errors_new was not present on origin, so this PR targets master.

Testing

• bash -n script/macos/bundle ✅

• cargo fmt ✅

• cargo test -p remote_server install_script ✅

  • 3 passed: tilde expansion regressions plus install_script_installs_lib_sidecar_without_changing_binary_path

• cargo clippy --workspace --all-targets --all-features --tests -- -D warnings ✅

• Built native arm64 CLI:

  • script/macos/bundle --nosign --channel dev --arch aarch64 --artifact cli ✅
  • xcrun swift-stdlib-tool copied 0 sidecar dylibs for arm64 on this toolchain.
  • otool -L target/release-cli-debug_assertions/bundle/osx/dev | grep libswiftCore shows /usr/lib/swift/libswiftCore.dylib.
  • otool -l target/release-cli-debug_assertions/bundle/osx/dev shows LC_RPATH entries for /usr/lib/swift and @executable_path/lib.
  • Packaged/extracted dev resources lib; /tmp/warp-cli-swift-validation-arm/dev --version returned Oz <unknown>.

• Built/validated x86_64 CLI under Rosetta:

  • script/macos/bundle --nosign --skip-build --channel dev --arch x86_64 --artifact cli ✅
  • Archive includes lib/libswiftCore.dylib plus 14 other libswift*.dylib sidecars.
  • otool -L target/release-cli-debug_assertions/bundle/osx/dev | grep libswiftCore shows @rpath/libswiftCore.dylib.
  • LC_RPATH order is /usr/lib/swift first, then @executable_path/lib, so modern macOS uses the system Swift runtime while older systems can fall back to the sidecar.
  • Packaged/extracted dev resources lib; arch -x86_64 /tmp/warp-cli-swift-validation-x86/dev --version returned Oz <unknown>.

• I have manually tested my changes locally with ./script/run

Overview

This PR updates the macOS CLI packaging flow to add Swift runtime rpaths, collect Swift stdlib sidecars into the bundle, include the sidecar lib/ directory in release archives, and install that directory alongside the remote-server binary. It also adds a focused installer regression test for the new sidecar layout.

Concerns

• No blocking correctness, error-handling, or security concerns found in the changed lines.
