ruff server respects per-file-ignores configuration

[snowsignal]

Summary

Fixes #11185
Fixes #11214

Document path and package information is now forwarded to the Ruff linter, which allows per-file-ignores to correctly match against the file name. This also fixes an issue where the import sorting rule didn't distinguish between third-party and first-party packages since we didn't pass in the package root.

Test Plan

per-file-ignores should ignore files as expected. One quick way to check is by adding this to your pyproject.toml:

[tool.ruff.lint.per-file-ignores]
"__init__.py" = ["ALL"]

Then, confirm that no diagnostics appear when you add code to an __init__.py file (besides syntax errors).

The import sorting fix can be verified by failing to reproduce the original issue - an I001 diagnostic should not appear in other_module.py.
