fix: P3 — normalize variable name drift across core modules

- *memory* → *memory-store* (context, perceive tests, defpackage export)
- *skills-registry* → *skill-registry* (context, reason)
- *logs-lock* → *log-lock*, *system-logs* → *log-buffer* (context → defpackage)
- *cognitive-tools* → *cognitive-tool-registry* (act)
- deterministic-verify → cognitive-verify (act → reason)
These were runtime errors — referenced variables that don't exist.
Harmless until called, but would crash if those code paths were hit.
