chore(release): 0.21.0

[kartikeya-27]

Release 0.21.0. All SDKs (Python, Node, Java) and the Rust crates ship in lock-step off one version.

Bumped via scripts/version.mjs --set 0.21.0 (root Cargo.toml source of truth + mirrors + Cargo.lock); docs changelog page and version badge regenerated by scripts/sync-changelog.mjs. scripts/version.mjs --check passes.

Highlights (since 0.20.0)

Added

• Log + cursor pub/sub — opt-in log topic mode, per-message ack, first-class topic registry, managed consumer.
• Retention on by default — per-table windows, elected reaper/cleaner, bounded purges on all backends.
• Overload controls — opt-in max_pending admission cap, CoDel load shedding, LIFO dispatch order.
• Per-task token-bucket retry_budget.
• Native async dispatch; headless taskito-tui; native Rust worker + typed Redis/JSON errors; cross-SDK per-task policy + batching parity; single-source release version.

Changed

• Keyset pagination and bounded scans at millions of rows; async backpressure; unified task lifecycle; PostgreSQL/Redis retention tuning.

Fixed

• Node webhook SSRF guard; Node webhook store aligned to the cross-SDK layout; log-consumer flush/shutdown fixes; negative result_ttl rejected; docs path prefix.

Full detail in CHANGELOG.md.

Verification

Full suite green locally: cargo fmt/clippy/test, Python ruff+mypy+pytest (1277 passed, 7 skipped), Node lint + 459 tests, Java ./gradlew build.

After merge

Tag 0.21.0, node-v0.21.0, java-v0.21.0 from master to trigger the publish workflows; taskito-core to crates.io is published manually.
