1.16.1 - Scanner configuration and funding link fixes

This patch fixes TypeScript configuration and manifest metadata reported by the plugin scanner. It does not change file operations, navigation, settings or the user interface.

Fixed

• Declare ES2019 standard-library types for Array.flatMap and Object.fromEntries, while keeping the ES2018 output target. The missing declarations caused the scanner to report unsafe assignments, calls, arguments and returns at those sites.
• Add a source-only TypeScript check without ambient Node types to the production build. Test dependencies can no longer hide missing standard-library declarations.
• Point fundingUrl to the repository's Support section, keeping the existing donation options accessible from one page.

Validation

• 725 automated tests passed, along with coverage thresholds, lint, both TypeScript checks and the production build.
• The generated main.js is byte-for-byte identical to 1.16.0. Runtime behavior and existing settings are unchanged.
• Minimum supported Obsidian version remains 1.8.7.
• The external scanner has not been rerun. Vault enumeration and clipboard access remain intentional explorer features; decorative underline CSS is unchanged.

Release assets: main.js, manifest.json and styles.css.
