chore: release 0.22.0

[pratyush618]

Version bump and changelog for 0.22.0. node scripts/version.mjs --set 0.22.0 rewrote the root Cargo.toml and every mirror; Cargo.lock, the docs changelog page and the landing-page version badge were regenerated rather than hand-edited.

No tags are pushed by this PR. Tagging (0.22.0, node-v0.22.0, java-v0.22.0) is a separate step once this merges.

Changelog

The ## Unreleased section became ## 0.22.0 with a lead paragraph. It was then audited against every commit in 0.21.0..HEAD — 59 of them — and corrected where it had drifted from the code:

• Event taxonomy is 29 names, not 26. EVENT_NAMES (Node), EventName wire values (Java) and EventType (Python) all count 29; fix: complete the predicate event taxonomy across SDKs #574 added three after that line was written.
• predicate.cancelled is no longer Python-only. Since fix: complete the predicate event taxonomy across SDKs #574 it is reserved in all three — subscribable, typed, webhook-matchable — but only Python emits it, because Node and Java gate at enqueue where a terminal skip is predicate.skipped. The entry said the name itself was Python-only.
• The Python periodic catalog has no add or update. The shipped surface is list_periodic,
  delete_periodic, pause_periodic, resume_periodic.
• The retry predicate is named retryOn — (error) => boolean in Node, Predicate<Throwable> in Java, with RetryableException / NonRetryableException as the exception-typed route.
• Batch unique_key dedup is not Node-only. It is the shared enqueue_batch_dedup helper in storage/mod.rs, used by both the Node and Java batch enqueues; a keyless batch keeps the chunked insert and Python still batch-inserts without dedup.
• The predicate taxonomy fix is about recognition, not emission. All three SDKs now carry the same set of names; what each emits still differs.

Fifteen merged changes had no entry at all and were added: the standalone taskito-server (#583, #584, #596), the taskito executor subcommand (#595), the executor side-channel (#599–#604), namespace scoping of the id-addressed storage APIs (#606, #614), dashboard settings compare-and-set (#605), the napi 3 upgrade (#581), the Java null-safety contract and platform coverage (#572, #569, #598), the predicate taxonomy fix (#574), retention dry-run and the dashboard's live-window echo (#509, #499), retry predicates (#498, #500), push-dispatch in the
Node and Java shells (#497), Node standalone health helpers (#545), Python periodic-catalog management (#502), Java classifier jars and GraalVM metadata (#510), the batched Redis metric purge (#617), and the Node CLI / Java install-doc version drift (#568).

Dependabot bumps, docs-only commits, one test-only fix (#609), one CI change (#616) and one internal refactor (#573) are omitted, matching how 0.21.0 was written.

Verification

• cargo fmt --all --check; cargo clippy --all-targets --all-features -- -D warnings; cargo test --workspace
• uv run ruff check taskito/ tests/; uv run mypy taskito/ tests/ --no-incremental (317 files); uv run python -m pytest tests/ -x -q — 1393 passed, 14 skipped
• pnpm lint && pnpm test — 673 passed, 6 skipped
• ./gradlew build — BUILD SUCCESSFUL
• node scripts/version.mjs --check — 13 manifests agree on 0.22.0

match errors using the exact task-name capture from the _RAISED lifecycle
record, rather than checking whether stoppable.name appears in the message.
Preserve the existing taskito record and ERROR-level scoping, and assert that no
