chore: upgrade to Evo SDK 4.0.0-rc.2 across tutorials and example apps

[thephez]

Summary

Moves the tutorials and all example apps onto @dashevo/evo-sdk 4.0.0-rc.2, pins the Node toolchain repo-wide so local and CI builds match, and hardens the example-app e2e suites that the upgrade shook loose.

SDK bump → 4.0.0-rc.2

• Root tutorials: package.json / package-lock.json.
• Example apps (dashmint-lab, dashproof-lab, dashnote, dashnote-starter): each pinned in its own package.json / lockfile.
• Zero-build companion pages (dashmint-lite.html, dashproof-lite.html, dashnote-lite.html): esm.sh imports aligned to the same version as their React app.
• Lockfile transitives refreshed across the example apps.

Node toolchain pinning

• New repo-root .nvmrc pinning Node to 22.22.
• engines.node range (>=22.22.0 <22.23.0) added to the root and every example-app package.json.
• All CI workflows now read node-version-file: .nvmrc instead of a hardcoded version, and log node/npm versions for diagnostics.

Test hardening

• dashmint-lab — the e2e auth flow selects a purchasable listing by its "Buy" button instead of owner-chip string matching, which broke once the test identity had a DPNS name.
• dashnote — the Playwright suite is resilient to lingering sonner toasts intercepting navigation, to the create→"Save" button transition lagging behind testnet eventual consistency, and is no longer coupled to a specific fixture title in the delete-flow test.

Other

• identity-withdraw-credits.mjs: raise the withdrawal amount to the protocol minimum (1,000,000 credits).

Summary by CodeRabbit

• New Features
  • Updated Evo SDK to 4.0.0-rc.2 across the example apps and browser demos.
• Bug Fixes
  • Adjusted the example identity withdrawal credits amount to better match the intended test scenario.
• Tests
  • Improved end-to-end test stability by refining UI timing/waits and strengthening dialog/button handling.
• Chores
  • Standardized CI/tutorial Node setup to use .nvmrc, and added/updated Node version engine constraints to match.

📝 Walkthrough

Walkthrough

@dashevo/evo-sdk is bumped from 4.0.0-rc.1 to 4.0.0-rc.2 across all package.json files and CDN HTML imports with engines constraints pinning Node.js to 22.22. Node.js version setup is migrated from hardcoded values to reading from .nvmrc across all CI workflows. The identity tutorial withdrawal amount is raised from 190000n to 1000000n. E2E tests in dashmint-lab and dashnote are updated to use more resilient UI selectors and add explicit waits for toasts, save-state label variants, and deletion dialog dismissal.

Changes

Node.js Version Pinning and SDK Upgrade

Layer / File(s)	Summary
Node.js version pinning and workflow configuration .nvmrc, .github/workflows/dashnote-e2e.yml, .github/workflows/dependency-update.yml, .github/workflows/deploy-example-apps.yml, .github/workflows/test-tutorials.yml	.nvmrc pinned to Node.js 22.22; all CI workflows updated to read Node version from .nvmrc instead of hardcoded values, with explicit version output steps added.
SDK version bump and engines constraints in packages package.json, example-apps/dashmint-lab/package.json, example-apps/dashnote-starter/package.json, example-apps/dashnote/package.json, example-apps/dashproof-lab/package.json	@dashevo/evo-sdk bumped from 4.0.0-rc.1 to 4.0.0-rc.2 in all packages; engines.node constraint added to each specifying >=22.22.0 <22.23.0.
SDK version bump in CDN HTML imports example-apps/dashmint-lab/public/dashmint-lite.html, example-apps/dashnote/public/dashnote-lite.html, example-apps/dashproof-lab/public/dashproof-lite.html	Evo SDK CDN imports updated to 4.0.0-rc.2 from earlier development versions.

Tutorial and E2E Test Updates

Layer / File(s)	Summary
Identity tutorial withdrawal amount increase 1-Identities-and-Names/identity-withdraw-credits.mjs	The amount constant is raised from 190000n to 1000000n.
E2E test stability improvements example-apps/dashmint-lab/test/e2e/auth.spec.ts, example-apps/dashnote/test/e2e/fixtures.ts, example-apps/dashnote/test/e2e/notes.spec.ts	Dashmint-lab listing selection picks by visible Buy button instead of identity-id prefix; modal assertion accepts "Insufficient credits". Dashnote fixtures add toast-clearing before navigation, accept both Save/Create-note labels, and wait for delete-confirmation dismissal. Mobile delete test opens first available note and scopes click to avoid hamburger overlap.

Poem

🐇 Hop, hop, hooray for rc.2!
The credits now flow with a million or two,
No more flaky toasts blocking the way,
Buy buttons and dialogs work come what may.
A cleaner test suite, a shinier dep —
This bunny approves every confident step! 🌟

Update the workaround note and re-verify the protocol override for rc.2.

The comment still says the override is for “evo-sdk dev.6”, but the import on Line 122 is now 4.0.0-rc.2. Please update the note to match reality and verify whether forcing { version: 11 } is still required.

In `@example-apps/dashnote/test/e2e/notes.spec.ts`:
- Around line 231-240: The test currently hard-fails with a timeout when no
notes exist for the current identity instead of skipping cleanly. Before
attempting to select the first note row using the locator pattern
`[data-testid^="note-row-foreground-"]`, add a check to count the number of note
rows available. If zero note rows are present, call the test skip function
(typically `test.skip()` or `this.skip()` depending on your test framework) to
skip the test deterministically rather than waiting for the timeout to occur.
