Prepare v1.0.0 release

[kirich1409]

Release v1.0.0 prep — into develop

Promotes the integration branch to release state for the first stable 1.0.0. Config/docs only — no code changes.

Changes

• gradle.properties: VERSION_NAME 1.0.0-Beta1 → 1.0.0 (hygiene/SNAPSHOT base; the actual Maven version at release is derived from the v1.0.0 tag by publish.yml).
• CHANGELOG.md: [Unreleased] → [1.0.0] - 2026-05-30; fixed the stale build-logic/ plugin bullet (Move Gradle plugin from build-logic/ to repo root #215 moved it to repo root); added a Platform stability subsection; filled gaps (Fix ConfigValues.observe to catch provider exceptions #196 observe provider-exception fix, Migrate user documentation to GitHub Wiki #193 docs→Wiki, Rename proguard task to generateFeaturedProguardRules #190 ProGuard task rename); fixed compare links.
• README.md: new Platform stability table — Android Stable; iOS (SKIE/DCE) & JVM Preview.
• CLAUDE.md + CONTRIBUTING.md: must-fix — removed the false claim that Binary Compatibility Validator auto-enforces API stability (BCV was removed in chore: remove binary-compatibility-validator (BCV) #150); CONTRIBUTING deprecation section rewritten to the real "no migration window" policy.

Positioning

Android — Stable; iOS (SKIE/DCE) & JVM — Preview (public API may change in minor releases without a major bump).

Verification (all green, local)

• assemble ✓ (serialized K/N link), test ✓, spotlessCheck ✓, :core:koverVerify ✓ (≥90%), :featured-gradle-plugin:test ✓, publishToMavenLocal ✓ (POM/BOM/coords/GPG), :core:zipXCFramework ✓.
• L5 runtime smoke: Android sample on Pixel 10 AVD ✓ (reactive flag toggle + Debug UI lists 5 flags via GeneratedFeaturedRegistry.all); Compose Desktop launch ✓; iOS FeaturedSampleApp.framework build ✓.

Next: release PR develop → main, then tag v1.0.0 (both require explicit confirmation).

Pull request overview

Release-prep PR that promotes the integration branch to 1.0.0 state. Docs/config only — bumps the publishing version, finalizes the changelog with platform-stability framing, adds a stability table to the README, and corrects two documents that still claimed Binary Compatibility Validator was enforced (it was removed in #150).

Changes:

• Bump VERSION_NAME from 1.0.0-Beta1 to 1.0.0.
• Finalize CHANGELOG.md [1.0.0] - 2026-05-30 (add #190/#193/#196 entries, fix #215 plugin-location bullet, add Platform stability subsection, fix compare links).
• Replace BCV claims in CLAUDE.md and CONTRIBUTING.md (rewrite deprecation section to the real "no migration window" policy) and add a Platform stability table to README.md.
