Release 0.32.1 (patch)

VERSION_NAME 0.31.2 → 0.32.1; CHANGELOG.md + README "What's New".

0.32.1 — the fix

  • GroupNorm compiles on stock IREE (fix(hlo): GroupNorm emits real stablehlo.reduce (IREE-compilable) #754). The 0.32.0 converter emitted @reduce_mean/@reduce_variance custom_calls that iree-compile can't lower. It now emits real stablehlo.reduce (variance as E[x²]−E[x]², ddof=0). Verified end-to-end via skainet-iree-conformance: iree-compile + iree-run-module + numpy validate → PASS max_abs_err=1.2e-7.

Note — supersedes #753

develop never received the 0.32.0 release back-merge: #753 was tagged + published to Maven but is blocked from merging by the base-branch policy, so develop's metadata was stuck at 0.31.2. This PR folds in the 0.32.0 CHANGELOG/README entries too (GroupNorm converter #752, SKEEP docs #750, quantization doc #747, dep bumps), bringing develop fully current in one mergeable PR. #753 can be closed as superseded.

🤖 Generated with Claude Code

Patch release. Bumps VERSION_NAME 0.31.2 -> 0.32.1 and brings the release
metadata current: develop never received the 0.32.0 release back-merge (PR #753
was tagged + published but blocked from merging), so this consolidates the 0.32.0
AND 0.32.1 CHANGELOG / README "What's New" entries (supersedes #753).

0.32.1 fix: GroupNorm now emits real stablehlo.reduce instead of
@reduce_mean/@reduce_variance custom_calls, so a groupNorm module compiles on
stock iree-compile. Verified end-to-end via skainet-iree-conformance:
PASS max_abs_err=1.2e-7. (PR #754)

0.32.0 (folded in): GroupNorm StableHLO converter (#752), SKEEP proposals docs
(#750), quantization-process doc (#747), dependency bumps.
