chore(release): Bump to v3.3.0

[nathanliow]

Highlights

• Parsed Events API (feat(parsed-events): add parsed events api and deprecate enhanced transactions #356): helius.parsedEvents replaces Enhanced Transactions on mainnet. helius.enhanced is deprecated for mainnet use.
• Parsed Streams client (feat(ws): add parsed streams client #358): decoded real-time transactions, filtered on the server, from helius-sdk/websockets/parsedStreams.
• Preconfirmation filters and coverage (feat(ws): add preconfirmation filters and getPreConfCoverage #363): server-side preconfSubscribe filters, getPreConfCoverage(), and unsubscribe now actually stops billing.
• MEV Protect (feat(txns): add mev protect support #357): opt-in, client-wide or per Sender call.
• Email-required agent signup (fix(auth): Validate signup contact info and deprecate wallet project creation #359): new-account signup / signupAndPay validate email, firstName and lastName. payUSDC throws. createProject, payUSDC and PAYMENT_AMOUNT are deprecated. This release has to be on npm before helius-labs/monorepo#20801 deploys, and fix(helius-mcp): Require email for agent signup core-ai#191 then bumps to it.
• Fixes: custom baseUrl with an existing query string (fix(rpc): append query params with & when baseUrl already has a query #352), purchaseCredits error wording (fix(auth): Describe Beyond-Allowance Usage as Autoscaling in purchaseCredits Error #353), dev-dependency advisories (fix(deps): patch js-yaml, browserlist, and baseline-browser-mapping #354, fix(deps): patch axios, brace-extension, markdown-it #355), enhanced client non-JSON error bodies (fix(enhanced): handle non-JSON error bodies #360), waiting WebSocket iterators now reject on disconnect (fix(websockets): reject a waiting iterator when the connection drops #362).

Semver

Minor. #356, #357, #358 and #363 add features. #359 changes behavior only for flows the backend no longer supports: new signups without contact info, and the 1 USDC wallet-only unlock. Nothing is removed from the public API. The deprecated exports are removed in the next major.

Changes

• package.json: 3.2.0 → 3.3.0
• CHANGELOG.md: v3.3.0 section covering fix(rpc): append query params with & when baseUrl already has a query #352–feat(ws): add preconfirmation filters and getPreConfCoverage #363, with the earlier Unreleased entries folded in

After merge

1. git tag v3.3.0 origin/main && git push origin v3.3.0. The release workflow then creates a draft release.
2. The workflow also opens an auto-changelog PR. Close it, because the changelog is already written here.
3. Publish the v3.3.0 draft release, which triggers npm publish.

Testing

pnpm format:check passes. No source changes. Rebased onto main at #363.
