Summary

main has been failing the CI lint and test jobs since 911ea34 because newer dependency versions changed behavior. Neither failure came from a code change in this repo.

• test: newer Streamlit resolves relative AppTest.from_file() paths against the calling test file. As a result, tests/test_pages_unsubscribe.py and tests/test_pages_verify.py looked for tests/immermatch/pages/*.py (13 failures). This anchors PAGE_FILE to the repo root, the same way tests/test_app_ui.py already does.
• lint: ruff 0.17 now formats Python code blocks inside Markdown. This applies that formatting to the model snippets in AGENTS.md (whitespace only).
• Python 3.14: switches the Python used by CI, the daily digest workflow, .python-version and the devcontainer image from 3.13 to 3.14. The supported floor (requires-python >=3.10, ruff py310) is unchanged.

Test plan

• make check on Python 3.14.4: 403 passed, ruff and mypy clean
• CI-equivalent commands locally: ruff check, ruff format --check, mypy immermatch/ daily_task.py, pytest --cov-fail-under=60 (68.6%)
• pre-commit hooks pass on both commits
• CI green on this PR

What changed in this PR

This PR repairs CI failures caused by dependency behavior changes and aligns development and automation environments on Python 3.14, while retaining Python 3.10 as the supported minimum.

Changes:

• Anchor Streamlit page-test paths to the repository root.
• Apply whitespace-only formatting to Python snippets in AGENTS.md.
• Switch CI, daily digest automation, and local development configuration to Python 3.14.

File	Description
tests/​test_pages_verify.py	Use an absolute path for the verification page test.
tests/​test_pages_unsubscribe.py	Use an absolute path for the unsubscribe page test.
AGENTS.md	Reformat Python snippets without changing behavior.
.python-version	Select Python 3.14 for local development.
.github/​workflows/​daily-digest.yml	Run daily digest automation on Python 3.14.
.github/​workflows/​ci.yml	Run all Python CI jobs on Python 3.14.
.devcontainer/​devcontainer.json	Use the Python 3.14 development container image.
