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.

-;; This module provides whitespace manipulation operations for cleaning and transforming whitespace in text.
-
-;; Functions include:
-
-;; - removing leading and trailing whitespace
-;; - collapsing multiple spaces to single spaces
-;; - deleting blank lines
-;; - converting whitespace to hyphens.
-
-;; All operations work on the current line, active region, or entire buffer depending on context.
-
-;; Bound to keymap prefix C-; w
-
+;; Whitespace cleanup under C-; w: trim line edges, collapse runs of spaces,
+;; delete blank lines, enforce a single blank line, and hyphenate whitespace.
+;; Commands choose region, buffer, or current line based on prefix/mark state.
