yaml-generate used identity `is False` for auto_visual_map and merge_hint_segments. Integer 0 and quoted "false" did not opt out, so discovery could still rewrite visual_map and hint merges still ran. Co-authored-by: jmjava <jmjava@gmail.com>

Problem
yaml-generatetreatsdiscovery.auto_visual_map: falseas the opt-out that keeps a committedvisual_map, anddiscovery.merge_hint_segments: falseas the opt-out that skips hint-driven segment / wiring merges.Those checks used identity
is False. YAML integer0and the quoted string"false"are not the booleanFalse, so discovery still ran (and could rewritevisual_map) and hint merges still applied.Change
discovery.auto_visual_map/discovery.merge_hint_segmentsto be YAML booleans atConfig.from_yaml.yaml-generateso a hint merge cannot inject0/"false"after load.false/trueand missing keys keep current behavior.Milestone:
milestones/discovery-bool-flags.mdTests
auto_visual_map: 0and"false".discover_visual_map/merge_hint_declared_segmentsraise instead of silently continuing.
