fix: pin SQLAlchemy>=2.0 in requirements.txt (CORE-63)

[octo-patch]

Fixes #13036

Problem

ComfyUI uses SQLAlchemy 2.0-only APIs (DeclarativeBase, mapped_column, Mapped) in app/database/models.py and app/assets/database/models.py. Without a minimum version constraint, pip can resolve SQLAlchemy 1.x, causing an ImportError that crashes startup before any try/except can intercept it.

Solution

Pin SQLAlchemy>=2.0 in requirements.txt to ensure pip installs a compatible version.

Testing

Verified that both app/database/models.py and app/assets/database/models.py use SQLAlchemy 2.0-only APIs (DeclarativeBase, mapped_column, Mapped), and the constraint aligns with what the codebase already requires implicitly.

The pull request updates requirements.txt to change the SQLAlchemy dependency from an unconstrained entry (SQLAlchemy) to a minimum-version constraint (SQLAlchemy>=2.0). No other dependency entries or their version constraints were modified.

🚥 Pre-merge checks | ✅ 5

✅ Passed checks (5 passed)

Check name	Status	Explanation
Title check	✅ Passed	The title accurately summarizes the main change: pinning SQLAlchemy to version 2.0 or higher in requirements.txt, with clear reference to the associated issue.
Description check	✅ Passed	The description clearly explains the problem (SQLAlchemy 2.0-only APIs causing import errors), the solution (pinning SQLAlchemy>=2.0), and verification of the fix.
Linked Issues check	✅ Passed	The PR successfully addresses all key objectives from issue #13036: identifying SQLAlchemy 2.0-only imports, preventing startup crashes, and ensuring users have a clear remediation path by pinning the minimum version.
Out of Scope Changes check	✅ Passed	The PR only modifies requirements.txt with the SQLAlchemy version constraint, which is directly related to resolving issue #13036 and contains no unrelated changes.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
