fix(indexer): override nodeModulesDir to auto in worker container
deno.json globally sets "nodeModulesDir": "manual" because the Fresh
app deploys with a package.json + npm install workflow on Deno Deploy.
The indexer worker has no package.json, so 'manual' mode left
node_modules empty and the runtime crashed with ERR_MODULE_NOT_FOUND
on @libsql/client/web.
Pass --node-modules-dir=auto on both the build-time 'deno cache' and
the runtime 'deno run' so Deno itself populates and uses node_modules,
independent of the project default. The Fresh build is unaffected.
