refactor(custom-case): extract per-word title-case decision

Lift the three-branch capitalize-this-word predicate out of cj/title-case-region
into cj/--title-case-capitalize-word-p; the command now loops word boundaries and
delegates the decision, dropping its cyclomatic complexity. The 32-test
characterization suite is unchanged and green. The function is reindented from
tabs to the 2-space house style in the same pass, which accounts for the line
churn; no behavior change.
