Summary

Expose the shared introductory imaging plot through the Galaxy plotting namespace and forward the optional asinh stretch to the Array renderer. This keeps assistant figures on the standard plotting/configuration path. Part of PyAutoLabs/autolens_assistant#168; depends on PyAutoLabs/PyAutoArray#661.

API Changes

Add autogalaxy.plot.subplot_imaging_dataset_intro and optional stretch to plot_array. Existing calls keep their defaults. See full details below.

Test Plan

• Full Galaxy suite: 1,442 passed, 6 skipped.
• Shared plotting/export checks: 58 passed across Array/Galaxy/Lens.
• COSMOS-Web notebook: all 10 code cells executed; model score 3717.19.

Full API Changes (for automation & release notes)

Added

• autogalaxy.plot.subplot_imaging_dataset_intro(dataset, output_path=None, output_filename="dataset_intro", output_format=None, colormap=None, stretch=0.01, radius=None, excluded_pixels=None) re-exports the Array compositor.

Changed Signature

• autogalaxy.util.plot_utils.plot_array(..., stretch=None), also exported as autogalaxy.plot.plot_array (and used by Lens).

Migration

• Optional stretch=0.01 gives an asinh display without changing data. Omission preserves existing behavior. Install with the matching Array feature/release; older Array wheels do not supply this API.

Development-only Heart override

The human authorized “Authorize development-only shipping for #168”, then approved the library revision and concurrent plotting-only work in PyAutoArray. No merge or release is authorized.

Current Heart RED reasons:

• PyAutoArray: 4 uncommitted source change(s)
• PyAutoGalaxy: 9 commit(s) behind origin
• PyAutoLens: 7 commit(s) behind origin

Additional stale reasons: release validation incomplete: no rehearsal for current source; release push credential check stale (pyautolabs-bot, 49h old).

This change does not repair Heart. Required CI and the library-first release gate remain in force.
