ci: example-typecheck job + deterministic example lockfiles

[0xjcf]

What

Adds an examples-typecheck job to CI and commits a pnpm-lock.yaml for all 8 top-level examples.

Why

Examples were relocated to top-level examples/ (#65) and dropped from the library's gated typecheck (they're self-contained, non-workspace members) — so nothing in CI caught example regressions (CodeRabbit flagged this on #65). This restores coverage.

The job

Per example: root pnpm install (library tsc + ignite-* sources), then pnpm install --ignore-workspace --no-link-workspace-packages + tsc --project <example>/tsconfig.json (the example tsconfigs map ignite-element/@ignite-element/* to local package source). Loops all 8, collects every failure, fails if any breaks (no fail-fast). Runs on the existing PR-into-beta triggers; the release job stays main-push-only.

Lockfiles

Committed for all 8 examples so the per-example installs are deterministic — adds the lit-html entry declared in #65 (xstate), reconciles the stale adapter lockfiles to their package.json, and adds previously-missing lockfiles for the apps/frameworks examples. Reflects the verified 8/8-typecheck state.

Verification

• All 8 examples typecheck locally (the exact commands the job runs).
• verify.sh --full green (no regression to the library lanes).
• This PR's own examples-typecheck job is the live proof in CI.
