Upstream migrated from npm to bun (bun.lock) in v8.90.0, so switch from
buildNpmPackage to stdenvNoCC with a bun-install fixed-output derivation
for node_modules. Drop the obsolete update.sh and missing-hashes.patch;
update via nix-update-script with the node_modules subpackage.
Bundle the CLI straight from TypeScript source via the `_ts-source`
export condition, since the upstream release build relies on a turbo
remote cache to supply each workspace dependency's prebuilt dist/.
