feat: verify_install check F — simulate the Colab bootstrap end-to-end

[Jammy2211]

Summary

Closes the last Colab maturity gap (PyAutoLabs/PyAutoBuild#124): nothing executed the Colab bootstrap path. New check F in the verify_install suite simulates a real Colab session end-to-end in a throwaway venv: pip install autolens jax from PyPI (emulating Colab's preinstalled env), a fake google.colab package so the on-Colab branch activates — including the output submodule that JAX's own colab_lib imports when it detects Colab (found by running the simulation, not by reading docs) — then the injected setup cell verbatim (pip install autoconf --no-deps → setup_colab.setup("autolens", workspace_dir=<tmp>) → workspace clone at the release tag) and one real notebook cell (al.Imaging.from_fits on dataset/imaging/simple).

While the installed autoconf predates the setup_colab registry the check reports SKIP — it self-activates at the next release. Requires the PyAutoConf workspace_dir override (PyAutoLabs/PyAutoConf#121, same branch name) — merge together; both ship in the same release.

First run already paid for itself: the simulated cell loaded a 15×15 image from the release tag — released workspace datasets are smoke-regeneration artifacts (30/49 at ≤15px). Filed as PyAutoLabs/PyAutoBuild#126.

Rider: check A/C workspace clones move off the stale Jammy2211 owner (redirects today, but it's the rot class the URL guards now forbid).

Closes #45.

API Changes

None — check suite + docs + tests only.

Test Plan

• python3 -m pytest tests/ — 237 passed (5 new in test_verify_install_script.py: bash syntax, help lists A–F, unknown-arg rejection, F wiring, no stale clone owner)
• SKIP path via the real script against current PyPI (F|SKIP … predates setup_colab registry; overall PASS)
• PASS path via the driver with next-release autoconf: fake google.colab accepted, GPU check reported CPU cleanly, stack installed --no-deps, workspace cloned detached at tag 2026.7.6.649 --depth 1, config pushed, cell loaded the dataset
• First fully-green run: after the next release, pyauto-heart verify_install F

Record correction: the PASS-path validation clone landed detached at tag 2026.5.29.4 (matching the pip-installed autolens — PyPI's current stack latest), not 2026.7.6.649. The tag-matched-clone mechanism is exactly what was being proven, and it held; only the tag name in the test-plan bullet was wrong.
