Summary

• Update the published Java SDK distribution to 3.2.0.
• Refresh the API reference, developer guide, release notes, legal notices,
  and sample sources.
• Preserve the new sample dependency layout (samples/lib and
  samples/common) and align README instructions with it.
• Exclude complete distribution ZIPs, SDK activation keys, private signing
  keys, PKCS#12/PFX containers, generated test-PKI material, and OS metadata.
• Add ignore rules and explain how users supply their own license and
  prepare local signing prerequisites.

Verification

• All 30 sample source sets compile using JDK 21 javac --release 8.
• Shell syntax and Python parsing checks pass.
• SDK JARs in lib and samples/lib are byte-identical (class-file major 52).
• SHA-256: 22a8c26e504ef2922f43f10184c0cb510f7faf06c5a300b35071846f88953689.
• Audited all 553 files in the commit index, including JAR entries, for
  excluded artifacts, private-key PEM markers, and matches to the source
  distribution's activation key; no matches remain.
• Extracted and scanned the text of all 11 bundled PDF files.
• Verified sensitive-file ignore rules and required JAR inclusion.

Limitations

• No licensed runtime samples, network signing services, or AWS operations
  were executed. Compilation is not end-to-end runtime acceptance.
• Signing examples require user-provided or locally generated credentials.
  See samples/README.md for the existing default mode and prerequisites.
• This update excludes complete ZIP distribution assets and does not
  create a release or tag.
• Repository history has not been rewritten or subjected to a full secret audit.
