### Problem to solve Meltano doesn't allow running commands from a subdirectory of a meltano project: ```bash cd transforms meltano invoke sqlfluff:lint `meltano invoke` must be run inside a Meltano project. Use `meltano init <project_name>` to create one. If you are in a project, you may be in a subfolder. Navigate to the root directory. ``` Given SQLFluff has [an outstanding issue](https://github.com/sqlfluff/sqlfluff/issues/601) that requires it to be run from the root of the DBT project to use DBT as the marcro executor, we have to work around this with: ```bash MELTANO_PROJECT_ROOT=/path/to/meltano/project meltano invoke sqlfluff:lint ``` ### Proposal Instead, we could have Meltano recurse up from the current directory looking for a Meltano project. It seems this was a feature that used to exist in Meltano but was reverted in #510 due to threading issues. I could be wrong here but my hunch is the problem at that time was the code was using `os.chdir` to change the working directory from the perspective of Python. I've searched the code and `os.chdir` no longer exists in the codebase, so I believe it's safe to [restore this feature](https://gitlab.com/meltano/meltano/-/merge_requests/515/diffs#8e8067d772989bfee158f1ccfa6e2a8fe41056ec_48_38).
