Keep npm ci reproducible before the platform packages exist, generate optional native dependencies during release assembly, and update GitHub Actions to Node 24-based action versions.

🟡 Changes recommended
The Node bindings currently allow panics from the core font registry to crash the process and the Node README contains contradictory statements about prebuilt binaries.

Pull request overview
Adds an initial minipdf npm package that exposes MiniPdf’s Rust conversion engine to Node.js via native (napi-rs) bindings, plus CI and publishing workflows to build and distribute precompiled addons across major desktop/server targets.
Changes:
- Introduce a new
minipdf-nodepackage with Rust napi bindings, JS/TS entrypoints, and basic Node tests. - Add GitHub Actions workflows for Node CI and multi-target npm publishing (initial token publish + staged/OIDC flow).
- Update repository ignore rules for Node/native build artifacts.

package publication is independently retryable after a partial failure. Ensure
retries skip packages whose versions are already staged, or otherwise isolate
failures so completed packages do not block subsequent runs; preserve
publication of every unstaged package.

In @.github/workflows/node-ci.yml:
- Line 29: Set persist-credentials to false for the actions/checkout steps in
both CI jobs, alongside the existing uses: actions/checkout@v6 entries, so
neither checkout leaves the GITHUB_TOKEN configured for subsequent commands.
In `@minipdf-node/test/index.test.js`:
- Around line 74-79: Update the platform fixture loop and its assertions in the
test to use the eight real platform package names, then build an independently
defined expected dependency map from those names and compare it with the
generated map. Remove the self-referential expected value derived from
prepareRelease and retain validation that the complete required platform set is
present.
- Line 66: Replace the TestContext.after cleanup hook in the test setup with an
API supported across all Node.js versions declared by minipdf-node/package.json,
or raise the package’s minimum Node.js version to 18.13.0 or newer. Preserve the
existing packageRoot cleanup behavior.

Catch font registry panics at the N-API boundary, classify caller errors, preserve clearer generated loader diagnostics, clarify prebuilt distribution docs, and make staged package attempts independent.
Disable persisted CI checkout credentials, align the Node engine floor with node:test cleanup APIs, and enforce the exact supported native package set during release preparation.
