### Bug Description Attempting to use `remote-build` while in a directory that has dangling symlinks fails. This failure mode should not be forced by the craft tool, but rather should become a failure by the consuming build tools that the craft tool invokes (if it even _is_ an error). ### To Reproduce Create a broken symlink in any project, commit it, and then attempt to run `remote-build`. For example, ``` ├── here -> to-here # `to-here` doesn't exist! └── snap └── snapcraft.yaml ``` ### part yaml ```shell Irrelevant ``` ### Relevant log output ```shell 2026-06-25 11:18:42.312 Starting snapcraft, version 9.0.0 2026-06-25 11:18:42.312 Log verbosity level set to BRIEF 2026-06-25 11:18:42.312 Setting up Project 2026-06-25 11:18:42.312 Project file found at '/home/imani/work/scratch/snap/snapcraft.yaml' 2026-06-25 11:18:42.312 Loading project file 'snap/snapcraft.yaml 2026-06-25 11:18:42.313 Setting up BuildPlan 2026-06-25 11:18:42.313 Build plan contains 1 build(s). 2026-06-25 11:18:42.315 Loading app plugin sdplug 2026-06-25 11:18:42.338 Forward environment variables 2026-06-25 11:18:42.338 Registering craft-sd source handlers 2026-06-25 11:18:42.338 Registering craft-sd services 2026-06-25 11:18:42.338 SD not enabled.
