chore(release): prepare RustFerry 0.1.0

[ShiroKSH]

Summary

• Prepare RustFerry 0.1.0 as a public pre-release with registry-first installation, complete crates.io metadata, release documentation, package enforcement, and honest platform limits.
• Rebase onto the current master, retaining its Calculator example, generalized Windows Android path handling, JNI library loading fix, and physical Android Calculator evidence. The superseded release-branch Android implementation was removed instead of duplicated.
• Release job-store file locks after their final shared owner drops, fixing sporadic immediate-reacquisition failures on macOS without weakening long-operation lock ownership.
• Replace loaded-runner-sensitive worker timing assertions with channel watchdogs that prove blocked output writers are not joined.
• Bring the new Calculator example into the exact =0.1.0 release dependency contract and add the basic integration target required by the repository example matrix.
• Scope the new Windows-only Android test fixtures so strict Clippy remains clean on Linux as well as Windows.

Base: 451eda6cc1587ac36a01d632828532b77c70e3d3. Head: 7177662224d6edabf85d25bd790dbce4b9d816f3.

The release branch was rebased after master advanced with five Calculator/Android commits. All affected local gates were repeated from the new base. The release diff contains no Android production-path changes; those generalized fixes come directly from master, with only test-module cfg scoping added here.

Changed files

• Release enforcement: .github/workflows/ci.yml, .github/workflows/draft-release.yml.
• Public/release documentation: README.md, CHANGELOG.md, docs/STATUS.md, docs/installation.md, docs/quickstart.md, docs/support-matrix.md, docs/release/crates.md, docs/release/packaging.md, docs/release/release-checklist.md, docs/release/github-release.md, and crates/cargo-ferry/embedded-docs/quickstart.md.
• Package metadata: root Cargo.toml and all nine publishable crate manifests.
• Job-store locking: crates/cargo-ferry/src/job_store.rs, crates/cargo-ferry/src/job_store/admin.rs.
• Private worker tests: crates/rustferry-worker-macos/src/session_output.rs, crates/rustferry-worker-macos/src/snapshot_session.rs.
• Calculator release coverage: examples/calculator/Cargo.toml, examples/calculator/tests/basic.rs.
• Android cross-platform test cfg: crates/rustferry-android/src/cargo_build.rs, crates/rustferry-android/src/signing.rs.

Local verification

• cargo fmt --all -- --check
• cargo check --locked --workspace --all-targets --all-features
• cargo test --locked --workspace --all-targets --all-features (passed in 121.8 seconds)
• cargo clippy --locked --workspace --all-targets --all-features -- -D warnings
• RUSTDOCFLAGS="-D warnings" cargo doc --locked --workspace --all-features --no-deps
• cargo test --locked --workspace --all-features --doc
• Rust 1.92 workspace all-target/all-feature check
• strict rustferry-android Clippy for x86_64-unknown-linux-gnu, plus 42 Windows Android tests
• release contract: version 0.1.0 and 30 exact internal dependency edges
• license inventory: 330 Cargo dependencies, 500 npm development dependencies, 25/19 reviewed license expressions, four reviewed license files
• 20 release-script tests, seven standalone example checks and basic tests, 20 cookbook pages, 248 local links, mdBook, and schema equality
• VS Code npm ci and npm run check with the real CLI: 17 test files passed; 74 tests passed and 8 skipped; package smoke produced a 73,636-byte VSIX with SHA-256 0a78dc77fef748249d5c483a3c25ecae2930ebb98a884b6c3e1c1fa6fd03f921
• Windows Extension Host smoke: ordinary Rust remained inactive; a Ferry workspace activated, discovered, validated, and refreshed successfully
• VS Code performance probes: CLI handshake median 9.207 ms, validation median 10.338 ms, 10,000-event parse median 4.616 ms
• fresh Windows source-checkout smoke: generated com.example.rustferryreleasesmoke; Doctor, Capabilities, Ferry Check, and Cargo Check passed; Android build completed in 63.7 seconds
• independent APK inspection: 189,924,295 bytes; SHA-256 a311c7852ebee2f6bb429731bea4cb932740f64cf4a99b12ca6b9b2361d5da1d; API 26/36; FerryActivity; ZIP integrity; 16 KiB alignment; v2/v3 signatures; classes.dex; exactly one arm64-v8a ELF; no connected device required

Packaging

• All nine archives were rebuilt from a clean release tree and contain 13-73 files each.
• Compressed sizes range from 56,038 bytes (rustferry-ssh) to 570,004 bytes (cargo-ferry).
• cargo package --workspace --exclude rustferry-worker-macos --locked passed with package verification enabled.
• cargo publish --workspace --exclude rustferry-worker-macos --dry-run --locked passed; every simulated upload was aborted by dry-run.
• scripts/check-release-archives.py --check-sources rebuilt the normalized dependency graph in a fresh target and passed all nine archives.
• Normalized manifests retain exact =0.1.0 internal registry dependencies and the required README and dual licenses.
• No target/Git metadata, environment files, logs, mobile or VSIX artifacts, signing material, API tokens, private repository coordinates, author email, or developer absolute paths were found in the archives.

Publish order: rustferry-core, rustferry, rustferry-codegen, rustferry-remote, rustferry-android, rustferry-apple, rustferry-github, rustferry-ssh, cargo-ferry. rustferry-worker-macos remains publish = false.

Direct crates.io API checks on 2026-08-13 return 404 for all nine names. No crates.io upload has been attempted.

Validation limits

The current base records one user-confirmed physical Android launch and Calculator interaction. The final release-source smoke above is artifact-only. Android emulator runtime, iOS Simulator runtime, physical-iPhone runtime, generalized physical-device install/run/log workflows, live SSH compilation, and a development-signed remote IPA remain unvalidated. This is a public pre-release, not a production-readiness claim.
