[query] clean-up unused fs methods

[ehigham]

Change Description

This PR refactors the filesystem abstraction layer to improve the URL handling interface. The main changes include:

• Convert FSURL from a trait to an abstract class with a generic type parameter
• Add a standard path component addition operator / to replace addPathComponent
• Remove redundant methods like readNoCompression, deleteOnExit, stripCodecExtension, and caching-related methods
• Rename getPath to simply path for cleaner access
• Update implementations in AzureStorageFS, GoogleStorageFS, HadoopFS, and RouterFS to use the new interface

These changes make the filesystem API more consistent and easier to use while removing unnecessary functionality.

Security Assessment

Is this override for clarity? It's not necessary.

[ehigham]

Could you explain why it's not necessary?
For clarity and better tool support. I've gotten into the habit of adding override to any member that overrides the superclass as intellij's tooling is much better at refactoring/renaming these. In the past when I've renamed/added or removed params/moved it didn't apply the changes to members not marked override which lead to complile errors and time wasting.

I've long wanted a way to enforce using the override keyword, as I agree with Ed about the benefits, but it's very hard to remember to add it every time without tooling support. This comment made me do another look around, and I think I found a way to do that. I'll give it a try shortly.
