build: pyproject migration, shared tooling (ruff/pylint/uv), lint cleanup & typing

[vidiecan]

Makes dspace_rest_client a first-class project aligned with the consumer repo's conventions (AGENTS.md, .pre-commit-config.yaml, pyproject.toml). Five threads, all behaviour-preserving — all 68 tests still pass.

What changed

1. Packaging → PEP 621 pyproject.toml (replaces setup.py)

• Static metadata, requests as the only core dep, solr + dev optional-dependency groups.
• Type hints live in the source (.py), which is how this repo consumes the library (submodule on sys.path); no py.typed/MANIFEST.in ceremony is carried for a package that is never pip-installed here.
• Dropped requirements.txt — fpdf/textblob/setuptools were unused cruft; runtime deps now live in pyproject. requirements-test.txt is kept (the consumer repo's CI installs it).

2. Shared toolchain (.pre-commit-config.yaml + [tool.*])

• Mirrors the consumer repo: mixed-line-ending, autopep8 --max-line-length=90, ruff, pylint --rcfile=pyproject.toml.
• [tool.ruff] / [tool.pylint] / [tool.autopep8] / [tool.mypy] copied and adapted from the consumer standard.

3. uv / uvx dev + CI workflow

• CI now runs ruff, pylint and mypy via uvx (no global installs); local dev via uvx/uv run.

4. CI jobs (.github/workflows/tests.yml)

• Added a lint job (ruff 0.12.7 + pylint 3.3.7, versions pinned to the consumer's) and a typecheck job (mypy, continue-on-error — see typing note). Existing pytest matrix (3.10 / 3.12) retained; pip cache re-keyed off pyproject.toml.

5. Lint cleanup + type hints — pylint 9.36 → 10.00 / 10, no behaviour change:

• wildcard imports → explicit imports + __all__ (client, __init__);
• extracted _is_valid_uuid(), stopped shadowing the builtin id;
• fixed a dangerous mutable default arg (proxies), list()/dict() literals, no-else-return, consider-using-in, inconsistent-return-statements, logging-not-lazy, pointless-string-statement, unused vars;
• collapsed a redundant WorkspaceItem override to inheritance;
• added type hints (from __future__ import annotations) across models.py / client.py.

Validation (local, CI-exact versions)

Check	Result
pytest	68 passed
ruff 0.12.7 (dspace_rest_client + tests)	clean
pylint 3.3.7 (--rcfile=pyproject.toml)	10.00 / 10
wheel build (uv build)	OK

Notes for the reviewer

• Supported Python is now >=3.10 (was >=3.8 in the old setup.py), and the classifiers were trimmed to match. This is intentional, not incidental: CI only tests 3.10/3.12, the consumer repo targets 3.10+, and upstream has moved to 3.13. It does not come from a runtime requirement — from __future__ import annotations keeps the new PEP 604 (X | None) hints lazy — it simply makes the metadata reflect what we actually test and support.
• Typing is phased/non-blocking on purpose. The typecheck job is continue-on-error: true. Baseline: ~54 mypy (default mode) / 289 --strict errors, to be burned down incrementally; the remaining ones are pre-existing dynamic patterns (e.g. params = None reassignment, optional self.solr), not regressions from the added hints.
• Deliberately deferred (config-suppressed with justification in [tool.pylint], tracked as follow-ups, not done here to keep the diff low-risk): splitting the 1482-line DSpaceClient god-class (too-many-lines / too-many-public-methods), and the mutable class-attribute defaults on the model classes.

Pull request overview

This PR modernizes the dspace_rest_client library by migrating packaging/configuration to pyproject.toml, aligning local tooling with shared repo standards (pre-commit, ruff, pylint, mypy), and updating CI to run lint + typecheck jobs alongside the existing pytest matrix. It also includes largely behavior-preserving lint cleanups and type-hint additions across the client/models.

Changes:

• Migrates packaging from setup.py/requirements.txt to PEP 621 pyproject.toml, adds MANIFEST.in + py.typed marker.
• Adds shared developer tooling (.pre-commit-config.yaml, ruff/pylint/mypy config in pyproject.toml) and CI lint/typecheck jobs using uvx.
• Performs lint-driven refactors and typing improvements in dspace_rest_client/client.py, dspace_rest_client/models.py, and package exports in dspace_rest_client/__init__.py.

• This is a mutable class attribute ({}), which is shared across instances if any code mutates it before __init__ assigns an instance attribute. Prefer an annotation-only attribute (or None) and initialize per-instance in __init__ (which you already do).

    metadata = {}

dspace_rest_client/models.py:246

• This is a mutable class attribute ({}), which is shared across instances. Since the base initializer sets self.metadata, this can be an annotation-only attribute to avoid an unnecessary shared default at the class level.

    metadata = {}

pyproject.toml:10

• Because this README is also the published package description, its installation requirements must be updated with the migration. It still advertises Python 3.x/3.8 and tells source users to install the now-deleted requirements.txt (README.md:13-26), so the documented install command fails and the Python requirement conflicts with >=3.10.

readme = "README.md"
requires-python = ">=3.10"

dspace_rest_client/client.py:561

• The new public annotation rejects a supported and tested call: this method deliberately treats action=None as “omit the action filter” (see tests/test_client_read.py:283-297 and the guard below), but the str annotation makes typed consumers fail that call now that the package ships py.typed. Include None in the parameter type.

dspace_rest_client/client.py:141

• The mutable-default problem remains because every client constructed without proxies receives the same class-level dictionary. Mutating one instance's client.proxies therefore changes the proxy configuration of other default instances; copy the default when assigning it.

        self.proxies = proxies if proxies is not None else self.PROXY_DICT
