chore(ai): sync lint-org script and wrap-it-up from claude-templates

Byte-identical pull of .ai/scripts/lint-org.el,
.ai/scripts/tests/test-lint-org.el, and the new Step 3 lint section in
.ai/workflows/wrap-it-up.org. Upstream: claude-templates 138f35f (feat)
and 4eba98c (docs).

+;;; lint-org.el --- org-lint sweeper for tracked org files  -*- lexical-binding: t; -*-
+;;
+;; Usage:
+;;   emacs --batch -q -l lint-org.el FILE.org [FILE.org ...]
+;;     apply mechanical fixes in place, emit judgment items on stdout for the
+;;     command layer to walk
+;;
+;;   emacs --batch -q -l lint-org.el --check FILE.org [FILE.org ...]
+;;     report only — categorize without modifying the file
+;;
+;;   emacs --batch -q -l lint-org.el --followups-file=PATH FILE.org
+;;     apply mechanical fixes; if any judgment items remain, append them to
+;;     PATH as an org section dated today.  Used by wrap-it-up to defer the
+;;     judgment walk to the next morning's review without blocking the wrap.
+;;
+;; Mechanical categories (auto-fixed):
+;;   item-number                       add [@N] directive to drifted bullets
+;;   missing-language-in-src-block     convert bare #+begin_src to #+begin_example
+;;   misplaced-planning-info           merge multi-line CLOSED:/DEADLINE:/SCHEDULED:
+;;   misplaced-heading (markdown-bold) **X.** at start of line → *X.*
+;;
+;; Judgment categories (emitted on stdout):
+;;   misplaced-heading (verbatim-*)    =*** Foo= inside body prose
+;;   link-to-local-file                broken file: links
+;;   invalid-fuzzy-link                broken *Heading refs
+;;   suspicious-language-in-src-block  unknown source-block language
+;;   (anything else)                   surfaced as judgment with checker name
+;;
+;; Output format on stdout:
+;;   first line:  ;; lint-org: file=<path> mechanical=<N>[ (would-fix)] judgment=<M>
+;;   each issue:  (:kind mechanical-fixed|judgment :line <N> :checker <symbol> :msg "..." [:preview t])

+;; Before modifying a file, a backup is copied to
