feat(artifacts): trace Mach-O dylib resolution in bundles
Add trace_dylib_resolution (CLI trace-dylib-resolution) to the artifact family. For the active Mach-O, or every executable in the active .app (the main app, XPC services, extensions, login items, helpers), it reports which file each dylib load reaches and how. A pure TypeScript reader decodes FAT and Mach-O load commands: LC_LOAD/WEAK/REEXPORT/LAZY/UPWARD_DYLIB, including the newer dylib_use_command encoding with weak, re-export, upward and delayed-init flags, plus LC_ID_DYLIB, LC_RPATH, LC_DYLD_ENVIRONMENT and code-signature presence. Malformed tables are reported with the failing command instead of being guessed. Resolution follows dyld: - @executable_path comes from each process root; - @loader_path comes from the loading image, or from the owner of the LC_RPATH entry being expanded; - @rpath searches the loader's rpaths first, then up the load chain; - dependencies load dependents-first in load-command order, once per process, and a matching install name reuses an already loaded image; - symlinks are followed inside the analyzed root, and escapes stop. Every candidate path is reported with its outcome. Each edge resolves to resolved, conditional (an outside-root candidate such as /usr/lib/swift precedes), unresolved, or undetermined. Absolute and shared-cache system paths are never checked against the host. Derived findings cover unresolved required or weak loads, absent earlier @rpath candidates (with library validation left unknown), and LC_DYLD_ENVIRONMENT. verify:macos-bundle now also: - checks every traced image against otool -l; - asserts each resolution status on a clang-built fixture that adds a missing Overrides rpath, an absolute rpath, and a delay-init library; - compares the predicted load order of two process roots with what dyld loads under DYLD_PRINT_LIBRARIES.
