fix: runtime crashes on bundled deploy (fetch binding + signal serialization) — 2.4.0

[OrFrederick]

Summary

Fixes two runtime bugs that crash the add-in on deploy/login (minified prod builds). Release 2.4.0. Runtime-only — no src/types/** changes.

1. TypeError: Illegal invocation on first API call (src/internal/call.ts)

Minified bundles emit module.fetch(url), calling native fetch with this=module. Fix: fetch.call(globalThis, url, …). Matches the patch already proven in production in a sibling app.

2. signal serialized into ExecuteMultiCall (src/internal/queue.ts)

The multicall batcher copied whole queue entries (incl. AbortSignal → {}, plus resolve/reject) into the JSON-RPC payload. Fix: send only { method, params } per call.

Tests

• TDD red→green for both fixes; full suite 37/37 (pnpm test).
• Built bundles verified: .call(globalThis present and calls.map(...) projection in both dist/index.js + dist/esm/index.js.

Review

Independent code review: no issues at/above threshold. Abort handling + result dispatch confirmed intact (original calls array untouched); params-omission is strictly cleaner; fetch.call(globalThis) correct on both node-ponyfill and browser paths.

Consumer follow-ups (separate, after publish)

• ecoapp-web: drop patches/@fairfleet__geotab@2.3.0.patch + omitSignalFromSerializedCalls middleware; bump to ^2.4.0.
• ecoapp-addin-dev: bump to ^2.4.0, then migrate to prod.
