feat: require Python 3.12 in PyAutoCTI

[Jammy2211]

Summary

• Require Python 3.12 or newer in PyAutoCTI package metadata.
• Advertise the required 3.12/3.13 support pair and remove 3.9-3.11 classifiers.
• Update the living installation overview while preserving the archival paper and historical traceback.

API Changes

Packaging compatibility change: new distributions require Python 3.12 or newer and declare Python 3.12/3.13 support. No Python symbols, signatures, or CTI runtime behavior change.
See full details below.

Test Plan

• Python 3.12.10: python -m pytest test_autocti/ — 271 passed.
• Python 3.13.13: isolated environment with locally built arcticpy==2.6 — 271 passed.
• Clean wheel METADATA: Requires-Python: >=3.12; only 3.12/3.13 Python classifiers.
• Living support-claim census clean; archival JOSS paper and historical Numba traceback unchanged.
• Smoke n/a: packaging/docs-only change, no runtime API change, and PyAutoCTI is outside the six-workspace smoke matrix.

Validation checklist (--auto run — plan was not pre-approved)

• Effective level: safe (header: supervised, feature/medium cap: safe → safe)
• Plan: on issue feat: require Python 3.12 in PyAutoCTI #100, written at start, unmodified since
• Gate: tests 271 passed on 3.12 + 271 passed on 3.13 · smoke n/a (packaging/docs-only) · review CLEAN · Heart YELLOW within launch acknowledgement
• Human: plan sound in hindsight?
• Human: diff matches plan (no scope creep)?
• Human: merge, amend, or reject — then log the outcome

Full API Changes (for automation & release notes)

Removed

• None.

Added

• None.

Changed Behaviour

• Distribution metadata now rejects Python below 3.12.
• Supported classifiers are Python 3.12 and 3.13.

Migration

• Upgrade to Python 3.12 or 3.13 before installing the next PyAutoCTI release.
• Users who must remain on older Python may pin the last compatible unyanked line (autocti==2024.11.13.2, to be rechecked at release time).
