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.

-;; Wrapping functions:
-;; - surround-word-or-region - wrap text with same delimiter on both sides
-;; - wrap-word-or-region - wrap with different opening/closing delimiters
-;; - unwrap-word-or-region - remove surrounding delimiters
-;;
-;; Line manipulation:
-;; - append-to-lines - add suffix to each line
-;; - prepend-to-lines - add prefix to each line
-;; - indent-lines - add leading whitespace (spaces or tabs)
-;; - dedent-lines - remove leading whitespace
-;;
-;; Most functions work on region or entire buffer when no region is active.
