Issue body

### Bug Description When using snapcraft 8.2.1, I find that repacking an existing snap by using the directory arg has regressed. Reverting snapcraft (to 8.0.5 in my case) allows this to work again. ### To Reproduce ``` snap download hello unsquashfs hello_42.snap snapcraft pack squashfs-root --output hello.snap ``` workaround: ``` snap download hello unsquashfs hello_42.snap cd squashfs-root snapcraft pack . --output ../hello.snap ``` ### Environment Ubuntu 24.04 ### snapcraft.yaml ```shell # n/a ``` ### Relevant log output ```shell 2024-04-29 15:05:47.128 Starting snapcraft, version 8.2.1 2024-04-29 15:05:47.128 Log verbosity level set to BRIEF 2024-04-29 15:05:47.128 Configuring application... 2024-04-29 15:05:47.128 Preparing application... 2024-04-29 15:05:47.129 Build plan: platform=None, build_for=None 2024-04-29 15:05:47.129 Project file 'snapcraft.yaml' not found in '/tmp/tmp.2ItMSEP6Oi'. 2024-04-29 15:05:47.129 Detailed information: The project file could not be found. 2024-04-29 15:05:47.131 Traceback (most recent call last): 2024-04-29 15:05:47.131 File "/snap/snapcraft/11471/lib/python3.10/site-packages/snapcraft/application.py", line 136, in _resolve_project_path 2024-04-29 15:05:47.131 return super()._resolve_project_path(project_dir / "snap") 2024-04-29 15:05:47.131 File "/snap/snapcraft/11471/lib/python3.10/site-packages/craft_application/application.py", line 242, in _resolve_project_path 2024-04-29 15:05:47.131 return (project_dir / f"{self.app.name}.yaml").resolve(strict=True) 2024-04-29 15:05:47.131 File "/snap/snapcraft/11471/usr/lib/python3.10/pathlib.py", line 1077, in resolve 2024-04-29 15:05:47.131 s = self._accessor.realpath(self, strict=strict) 2024-04-29 15:05:47.131 File "/snap/snapcraft/11471/bin/../usr/lib/python3.10/posixpath.py", line 396, in realpath 2024-04-29 15:05:47.131 path, ok = _joinrealpath(filename[:0], filename, strict, {}) 2024-04-29 15:05:47.131 File "/snap/snapcraft/11471/bin/../usr/lib/python3.10/posixpath.py", line 431, in _joinrealpath 2024-04-29 15:05:47.131 st = os.lstat(newpath) 2024-04-29 15:05:47.131 FileNotFoundError: [Errno 2] No such file or directory: '/tmp/tmp.2ItMSEP6Oi/snap' 2024-04-29 15:05:47.131 2024-04-29 15:05:47.131 During handling of the above exception, another exception occurred: 2024-04-29 15:05:47.131 Traceback (most recent call last): 2024-04-29 15:05:47.131 File "/snap/snapcraft/11471/lib/python3.10/site-packages/snapcraft/application.py", line 139, in _resolve_project_path 2024-04-29 15:05:47.131 return super()._resolve_project_path(project_dir) 2024-04-29 15:05:47.131 File "/snap/snapcraft/11471/lib/python3.10/site-packages/craft_application/application.py", line 242, in _resolve_project_path 2024-04-29 15:05:47.131 return (project_dir / f"{self.app.name}.yaml").resolve(strict=True) 2024-04-29 15:05:47.131 File "/snap/snapcraft/11471/usr/lib/python3.10/pathlib.py", line 1077, in resolve 2024-04-29 15:05:47.131 s = self._accessor.realpath(self, strict=strict) 2024-04-29 15:05:47.131 File "/snap/snapcraft/11471/bin/../usr/lib/python3.10/posixpath.py", line 396, in realpath 2024-04-29 15:05:47.131 path, ok = _joinrealpath(filename[:0], filename, strict, {}) 2024-04-29 15:05:47.131 File "/snap/snapcraft/11471/bin/../usr/lib/python3.10/posixpath.py", line 431, in _joinrealpath 2024-04-29 15:05:47.131 st = os.lstat(newpath) 2024-04-29 15:05:47.131 FileNotFoundError: [Errno 2] No such file or directory: '/tmp/tmp.2ItMSEP6Oi/snapcraft.yaml' 2024-04-29 15:05:47.131 2024-04-29 15:05:47.131 During handling of the above exception, another exception occurred: 2024-04-29 15:05:47.131 Traceback (most recent call last): 2024-04-29 15:05:47.131 File "/snap/snapcraft/11471/lib/python3.10/site-packages/craft_application/application.py", line 263, in get_project 2024-04-29 15:05:47.131 project_path = self._resolve_project_path(self.project_dir) 2024-04-29 15:05:47.131 File "/snap/snapcraft/11471/lib/python3.10/site-packages/snapcraft/application.py", line 141, in _resolve_project_path 2024-04-29 15:05:47.131 return super()._resolve_project_path(project_dir / "build-aux" / "snap") 2024-04-29 15:05:47.131 File "/snap/snapcraft/11471/lib/python3.10/site-packages/craft_application/application.py", line 242, in _resolve_project_path 2024-04-29 15:05:47.131 return (project_dir / f"{self.app.name}.yaml").resolve(strict=True) 2024-04-29 15:05:47.131 File "/snap/snapcraft/11471/usr/lib/python3.10/pathlib.py", line 1077, in resolve 2024-04-29 15:05:47.131 s = self._accessor.realpath(self, strict=strict) 2024-04-29 15:05:47.131 File "/snap/snapcraft/11471/bin/../usr/lib/python3.10/posixpath.py", line 396, in realpath 2024-04-29 15:05:47.131 path, ok = _joinrealpath(filename[:0], filename, strict, {}) 2024-04-29 15:05:47.131 File "/snap/snapcraft/11471/bin/../usr/lib/python3.10/posixpath.py", line 431, in _joinrealpath 2024-04-29 15:05:47.131 st = os.lstat(newpath) 2024-04-29 15:05:47.131 FileNotFoundError: [Errno 2] No such file or directory: '/tmp/tmp.2ItMSEP6Oi/build-aux' 2024-04-29 15:05:47.131 Recommended resolution: Ensure the project file exists. ``` ### Additional context _No response_
