feat(config): P3 config batch — group 3 (cycle_bullets)

cycle_bullets (default off): when an unordered list item changes indent level
(gll/glh), rotate its glyph through the configured bullet_types as a depth-keyed
ring buffer — change_level_edit gains cycle_bullets + bullet_types params,
locates the marker via find_marker_span, and rewrites the glyph to
bullet_types[new_depth % len] for single-char unordered markers. Ordered
markers are untouched. list_change_level reads both from the wiki config.

Tests: cycle_bullets_rotates_glyph_on_indent + cycle_bullets_off_leaves_glyph.
