Sets the version to 0.2.0 for this brick's second release, following the pattern of #25 (v0.1.0). Plan §12 question 33.

Summary

• pyproject.toml: version = "0.2.0". The normalization brick stays pinned to its v0.2.0 tag, still its latest release.
• docs/plan.md: §10 gains the masks milestone (question 32, which Masks: pair every image with its masks and describe how they relate (plan §12 Q29) #26 did not list there) and the release; the folder-step line no longer says "not released yet"; new question 33 records what v0.2.0 holds.
• AGENTS.md: status: "Released as v0.2.0" with P4 (Image type, fluorescence or RGB, in step 2 and the manifest (P4) #28), P5 (Intensity checks and plots from the histogram table (P5) #29), the folder step without the design (Let other bricks embed the folder step without the experiment design #27) and the masks (Masks: pair every image with its masks and describe how they relate (plan §12 Q29) #26); next: the masks' notebook step and saved answers, later 3D and time-lapse masks.

What v0.2.0 holds (since v0.1.0)

• Image type, fluorescence or RGB (Image type, fluorescence or RGB, in step 2 and the manifest (P4) #28, question 29).
• Intensity checks and plots (Intensity checks and plots from the histogram table (P5) #29, question 30).
• folder_step(show_design=False) for embedding bricks such as MorphoRelate (Let other bricks embed the folder step without the experiment design #27, question 31).
• Masks: pairing, header checks, the masks command and mask_relationships.json (Masks: pair every image with its masks and describe how they relate (plan §12 Q29) #26, question 32). New core dependency: SciPy.

Outputs: plane_histograms.csv schema 3, experiment_design.csv schema 1, manifest version 1 with the optional keys image_type, channels_from_rgb_samples, intensity_checks and masks.

Notes for review

• After merging, tag the merge commit v0.2.0 (as for v0.1.0); MorphoRelate (MorphoRelate#183) and the other bricks then pin it. I did not tag.
• The notebook's Step 0 keeps its own current_version = "0.0.1" (the notebook's version, not the package's), unchanged as in v0.1.0.
• Not verified: the notebook in a real JupyterLab.

Tests

• Locally (Windows 11, Python 3.12, zarr 3.4.2, all extras), installed package reports 0.2.0: 1023 passed, 3 skipped (POSIX-only and case-sensitive file-system tests); ruff check . and ruff format --check . clean.
• CI: GitHub Actions on this PR.
