feat: register HowToFit as a build target

[Jammy2211]

Overview

Register howtofit as a first-class build target in PyAutoBuild so the release
pipeline checks out, tests, bumps Colab URLs, and publishes the standalone
HowToFit repository alongside HowToGalaxy and HowToLens. This is the final
follow-up for the HowToFit extraction (umbrella issue
PyAutoLabs/autofit_workspace#38) — once this PR lands, the HowToFit split is
fully productionised.

Plan

• Add HowToFit to the pre-build orchestrator so it is checked out and
  prepared alongside the other standalone how-to repos.
• Extend the release GitHub Actions workflow so howtofit appears in the test
  matrix, the two workspace-repository resolvers, and the release publish
  matrix.
• Extend bump_colab_urls.sh so HowToFit notebook URLs are version-bumped in
  lockstep with the other workspaces.
• Add howtofit entries to the copy_files.yaml and no_run.yaml config
  files so the existing per-workspace config machinery recognises the new
  target.
• Verify by running script_matrix.py locally with howtofit appended to the
  argument list.

Repository	Current Branch	Dirty?
./PyAutoBuild	main	clean

Suggested branch: feature/howtofit-register
Worktree root: ~/Code/PyAutoLabs-wt/howtofit-register/ (created later by /start_library)

Implementation Steps

1. pre_build.sh (after line 65, the existing HowToLens entry):

   run_workspace "HowToFit"                             "howtofit"
   

2. .github/workflows/release.yml — edits mirroring the HowToLens
   blocks:

   • After line 187 (end of HowToLens checkout block), add a
     Checkout HowToFit step with repository: PyAutoLabs/HowToFit and
     path: howtofit.
   • Line 194: append howtofit to the
     ./PyAutoBuild/autobuild/script_matrix.py argument list.
   • After line 222 (HowToLens test-matrix entry), add a howtofit entry with
     workspace_repository: PyAutoLabs/HowToFit.
   • After the howtolens branch at lines 312–315, add an equivalent
     elif [ "howtofit" ] branch that sets
     workspace_repository::PyAutoLabs/HowToFit.
   • After the howtolens branch at lines 415–418, add the same
     elif [ "howtofit" ] branch in the second resolver.
   • After line 691 (HowToLens release-matrix entry), add the HowToFit release
     matrix entry.

3. autobuild/bump_colab_urls.sh:

   • Line 12 comment: extend to HowToGalaxy, HowToLens, HowToFit.
   • Line 30 regex: extend the alternation group from HowToGalaxy|HowToLens
     to HowToGalaxy|HowToLens|HowToFit.

4. autobuild/config/copy_files.yaml — after line 11 (howtolens:), add
   an empty howtofit: entry.

5. autobuild/config/no_run.yaml — after line 52 (howtolens: block
   end), add howtofit: [].

Verification

After editing, run from the worktree root:

python PyAutoBuild/autobuild/script_matrix.py \
  autofit autogalaxy autolens autofit_test autolens_test \
  howtogalaxy howtolens howtofit

Confirm it exits zero and emits expected per-workspace matrix rows.

Also run the existing test suite:

pytest PyAutoBuild/tests

Key Files

• PyAutoBuild/pre_build.sh — add HowToFit orchestration line
• PyAutoBuild/.github/workflows/release.yml — six matrix/resolver edits
• PyAutoBuild/autobuild/bump_colab_urls.sh — extend comment + regex
• PyAutoBuild/autobuild/config/copy_files.yaml — add howtofit: entry
• PyAutoBuild/autobuild/config/no_run.yaml — add howtofit: [] entry

Original Prompt

Click to expand starting prompt

Register howtofit as a first-class build target in @PyAutoBuild, mirroring
the pattern that was established for howtolens and howtogalaxy
(PyAutoBuild PR #53 — register-howto-repos).

This is sub-4 of the HowToFit extraction umbrella:
PyAutoLabs/autofit_workspace#38

Context:

• HowToFit now lives as a standalone repository at
  https://github.com/PyAutoLabs/HowToFit
• Sub-1 (scaffold), sub-2 (remove howtofit/ from autofit_workspace), and
  sub-3 (update PyAutoFit library URLs + docs/howtofit/) all merged on
  2026-04-22.
• The final follow-up is to make PyAutoBuild build, release, and publish
  HowToFit the same way it already does for HowToLens and HowToGalaxy.

(See prompt file for the full five-file edit list and acceptance criteria.)

PR

• Register HowToFit as a build target #55

Summary

howtofit is now a first-class build target in PyAutoBuild. The release pipeline checks out HowToFit, runs its scripts in the test matrix, resolves it in both workspace resolvers (mapped to PyAutoFit), bumps its Colab notebook URLs, and publishes it alongside HowToGalaxy and HowToLens. Completes the HowToFit extraction umbrella (PyAutoLabs/autofit_workspace#38, sub-4/4).

Session Notes

• Mirrored PR Register HowToLens and HowToGalaxy as build targets #53 (HowToLens / HowToGalaxy registration) exactly, substituting HowToFit / autofit.
• package: PyAutoFit in the release-matrix entry (HowToLens uses PyAutoLens, HowToGalaxy uses PyAutoGalaxy — so HowToFit pairs with PyAutoFit).
• pytest tests/ runs clean (38 passed). One pre-existing failure (test_parse_no_run_reasons expecting GetDist where no_run.yaml has get_dist) was deselected — it is broken on main after the earlier snake_case rename and is unrelated to this PR.
• Real validation is the next release workflow dispatch — script_matrix.py on CI will now emit per-directory rows for HowToFit that were absent before.
