docs: fix blank package summaries and normalize more module headers

More of the commentary/comment audit. The custom-* command modules, weather-config, and mousetrap-mode had empty package summary lines and verbose summary paragraphs. I filled the summaries and condensed the prose while keeping each module's load-contract metadata. dwim-shell-config and auth-config had malformed ;; headers (now ;;;), local-repository had a leading BOM, and two test files had blank summaries.

-;; Array/list formatting:
-;; - arrayify/listify - convert lines to comma-separated format (with/without quotes, brackets)
-;; - unarrayify - convert arrays back to separate lines

-;; Line manipulation:
-;; - toggle-quotes - swap double ↔ single quotes
-;; - reverse-lines - reverse line order
-;; - number-lines - add line numbers with custom format (supports zero-padding)
-;; - alphabetize-region - sort words alphabetically
-;; - comma-separated-text-to-lines - split CSV text into lines

-;; Convenience functions: listify, arrayify-json, arrayify-python
