The profile pass map-reduced every session gist (~851) on every consolidation
firing — the biggest redundant-work and MI50-heat source left after the eras fix.
Now: skip when nothing's new, fold only the gists added since last build into the
existing profile, and full-rebuild only when there's no profile, too much has
accumulated to fold safely (>FOLD_LIMIT), on a periodic cadence (anti-drift), or
when forced.

Derive a standing profile of the user from session gists and inject it into
every prompt, so identity/abstract questions ("what kind of player am I",
"what are my leaks") are answered from distilled knowledge instead of noisy
single-vector recall (which finds passages, not patterns).
- memory: profile table + get/set_profile, list_summaries
- lyra/profile.py: rebuild_profile map-reduces all gists (batch -> extract
durable facts -> fold-merge) into one profile doc; `lyra-profile` CLI
- chat.build_messages injects "What you know about Brian" after the persona
Run after lyra-summarize (needs gists). Verified (stubbed): map-reduce, storage,
and prompt injection.
