chore(release): bump version to 0.2.2

[AlexanderWagnerDev]

Summary

• Bump crate version 0.2.1 → 0.2.2 in Cargo.toml/Cargo.lock.
• Add a [0.2.2] CHANGELOG.md entry covering the cluster security hardening landed since 0.2.1 (CLUSTER_SECRET validation + auth lockout, media-plane Subscribe gating, admin_proof replay protection, join SSRF protection, plaintext heartbeat hijack protection) and the dual-role RTT/stats and multi-arch Docker build fixes.

Test plan

• CI (clippy/fmt/tests) on this PR — local cargo check could not run in this sandbox due to a pre-existing toolchain version mismatch (rustc 1.94.1 installed vs. rust-version = "1.95" required), unrelated to this change.

📝 Walkthrough

Walkthrough

The release metadata updates the package to version 0.2.2, upgrades librtmp2 to 0.8.0, and documents security hardening, fixes, Docker build changes, and updated comparison links.

Changes

0.2.2 release metadata

Layer / File(s)	Summary
Package version and dependency update Cargo.toml	The package version changes to 0.2.2. The librtmp2 dependency changes to 0.8.0 while retaining TLS and the local override.
Release changelog and comparison links CHANGELOG.md	The changelog adds the 0.2.2 security, fix, and dependency entries. The version comparison links are updated.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🔵 Low · up to 6e3c0

The release metadata is localized, but the intended local librtmp2 dependency override may not take effect because it targets the wrong source. The PR is otherwise mergeable with explicit owner follow-up to correct or accept this bounded integration risk.

CI is red on RTMP + HTTP integration (and any other job that runs cargo test/cargo build) because commit 8de0e20 bumped the librtmp2 dependency requirement to ^0.8.0, but librtmp2 0.8.0 is not yet published on crates.io (only up to 0.7.0 is available there today):

error: failed to select a version for the requirement `librtmp2 = "^0.8.0"`
candidate versions found which didn't match: 0.7.0, 0.6.0, 0.5.0, ...

This is expected and not a regression in this PR's own code — it's a deliberate, ahead-of-time bump requested so this PR tracks librtmp2 0.8.0 once released. It will resolve automatically (via the update-cargo-lock workflow) once the v0.8.0 tag is pushed on OpenRTMP/librtmp2 and its publish-crates-io job completes. No fix to push here in the meantime.
