chore(@nylas/react): upgrade @nylas/web-elements to 2.6.0

[AaronDDM]

Bumps @nylas/web-elements in packages/react from 2.5.18 to 2.6.0, plus a patch changeset for @nylas/react. Same shape as the automated bumps (#92, #90, #88), opened by hand.

Why this wasn't automatic

nylas/nylas's update-nylas-javascript-web-elements job only runs when the release that just completed lists @nylas/web-elements in its publishedPackages. 2.6.0 published in an earlier release run than the one that eventually went green, so by the time a run succeeded web-elements was already on npm and correctly reported as "not being published" — the bump job saw no web-elements in that run's output and skipped.

Background: the original release was blocked because a Version Packages merge failed on an unrelated @nylas/notebook Cloudflare deploy (nylas/nylas#971 fixes that), and then NPM_TOKEN lacked publish rights to @nylas/core, @nylas/identity and @nylas/login-component. That token access has since been granted and all four packages are now published.

Verification

@nylas/web-elements@2.6.0 depends on @nylas/core@^1.4.0 and @nylas/identity@^3.2.0. Both are now on npm, so the install resolves — it did not until those published, which is why this PR was held back.

• pnpm install --no-frozen-lockfile — clean
• pnpm build — passes
• pre-commit format / lint / typecheck — pass (the lint warnings shown are pre-existing on main)

Lockfile changes are limited to the expected three:

-  '@nylas/web-elements@2.5.18'   +  '@nylas/web-elements@2.6.0'
-  '@nylas/core@1.3.0'            +  '@nylas/core@1.4.0'
-  '@nylas/identity@3.1.0'        +  '@nylas/identity@3.2.0'
