chore(typescript): upgrade to TypeScript 6 and modernize moduleResolution

TypeScript 6.0 is the newest release typescript-eslint supports (peer
range `>=4.8.4 <6.1.0`). TypeScript 7 is not viable yet: the plugin
hard-errors with "typescript-eslint does not support TS 7.0", and
vite-plugin-dts crashes reading the compiler API that the Go-based 7.0
package no longer exposes.

`moduleResolution` moves from the deprecated `node`/node10 to `bundler`,
which matches how Vite actually resolves this library and clears the
TS5107 deprecation error that 6.0 raises.
