update deps, add @jbrowse/quick-lru, pin eslint to v9

Add explicit Promise<Stats> return type to LocalFile.stat() so the
generated .d.ts references the duck-typed Stats interface from
filehandle.ts instead of import("fs").Stats. This means consumers no
longer need @types/node to type-check against this package.

Also add rootDir to tsconfig (required by TS6) and pass
--moduleResolution bundler to the CJS build to match the pattern used
in other packages in this org.
