chore(main): release E4A.PostGuard 0.6.0

[github-actions]

🤖 I have created a release beep boop

0.6.0 (2026-07-27)

⚠ BREAKING CHANGES

• NetworkException.Body was removed in fix: stop leaking raw upstream body in NetworkException (#41) #43 (GHSA info-exposure fix) but landed as a plain fix:, so release-please computed 0.5.1. The public-API tracking added in build: track the public API surface with PublicApiAnalyzers #52 records the removal as REMOVED; this marker corrects the next release to reflect it.

Bug Fixes

• emit inclusive range-end in Cryptify Content-Range header (#34) (73c2e43), closes #28
• harden ZIP entry-name handling in ZipHelper (#42) (2ffe84e)
• NetworkException no longer exposes raw upstream response bodies (7d2e1fb)
• reject duplicate recipient policy keys in BuildPolicyJson (#48) (f5ad9b8)
• stop leaking raw upstream body in NetworkException (#41) (#43) (135dee3)
