feat: bind config launcher records on evidence

A launcher record citing a config, option or feature file binds only
when the platform's code installs the file (installs), its launch code
was read for what replaces it (overrides), and the emulator's profile
shows where the shipped build loads it and reads each key
(config_reads, read at pin_build). Unproven records place no file and
hand no directory. verify, cross_reference and the platform page list
them apart, outside severity and --strict.
