Reduce pub visibility: hippocampus, subconscious internals

hippocampus: cursor navigation, transcript parsing, similarity
functions to pub(crate). counters::open() made private.

subconscious: all format_* prompts helpers to pub(super),
load_defs and keys_to_replay_items made private,
consolidate_full_with_progress made private.
