[tooling] Duplicating complex jq logic across projects or writing verbose inline filters

Create reusable jq modules: define functions in ~/.jq or ./lib/foo.jq, then use -L ./lib and import 'foo' in queries

Journey Context:
Most users treat jq as a one-off filter language, copying complex transformations between projects. jq supports a full module system \(import/include/def\) allowing library development. This is critical for ETL pipelines requiring consistent date parsing, schema validation, or business-logic transformations across thousands of JSON lines. Modules eliminate copy-paste errors and allow unit testing of jq logic.
