Release PR for v0.3.2. It sets pyproject.toml to 0.3.2 and records in AGENTS.md and in plan question 37 what the release holds. There is no code change.

v0.3.2 holds the fixes from the data-flow audit of 29 October 2026 (#35–#39):

• Refuse negative mask labels (background was counted as an object) #40: negative mask labels are refused.
• Report a malformed OME-Zarr labels group as unreadable_mask #41: a malformed OME-Zarr labels group is reported as unreadable_mask.
• Make differing channel names at one channel number an error #42 and Read and write channel_names_trimmed as a strict manifest flag #45: differing channel names are an error. Names are compared exactly after trimming leading and trailing whitespace, and the trim is recorded per file as channel_names_trimmed.
• Give masks a plane identity (Z/T); refuse 2D masks of multi-plane images #43: masks get a Z/T plane identity, and a 2D mask for a multi-plane image is refused.
• Data-flow audit minor findings: unknown scale, manifest flags, per-file roles, uint64 labels #44: manifest flags are strict, files get per-file roles, and uint64 labels are handled.
• Refuse images in a folder that also holds subfolders #46: a folder that holds both images and subfolders is an error.
• Pin the normalization brick to its release v0.3.2 #47: the normalization brick is pinned to v0.3.2, whose reader checks each row's plane_id, image_file and bit_depth.

After this PR is merged, the owner publishes the tag v0.3.2 on the merge commit. Every brick then moves its pin to it (D79).
