Add analysis profiles with distance/proximity-aware axes

A discrete verdict collapses magnitude and a generic axis can hide what you're
calibrating (a blowjob where the head is 20cm away still reads sexual_act=oral ->
MATCH). New 'profile' input selects an act-specialized axis set (general / oral /
penetration / handjob / solo) whose act-critical axes capture distance explicitly
(mouth_genital_distance: touching/<5cm/10-20cm/>20cm, oral_depth, insertion_depth,
stroke_position, ...). axes now overrides the profile when set. agent_bridge gains
--profile; workflows + docs updated.
