docs: volition, planning, agency and cognitive research

New documents define goal, want, intention, commitment, plan, action,
capability, authority, agency and introspection operationally, state
prominently that no operational measure establishes phenomenal
consciousness or sentience, and describe the rules, thresholds, events,
inspection points and limits of each subsystem:

- docs/volition.md: want derivation, reinforcement, decay and suppression,
  conflicts, formation and its outcomes, the intention–action gap,
  reconsideration, commitments and volition metacognition;
- docs/planning.md: plans and step kinds, validation, strategies, the
  executor, observe–act–verify, replanning, budgets, operator attention,
  long-running work, restarts and duplicates;
- docs/agency.md: the fifteen authority invariants and their tests,
  scoped authority, forensic why, attribution and the agency timeline;
- docs/cognitive-research.md: operational definitions separating
  implementation property from philosophical interpretation, experiment
  protocols (global workspace, ablation, self-model, counterfactual, model
  comparison, conflict), every measure, introspection accuracy,
  metacognitive calibration and temporal self-continuity.

Updated: interpretation table, capabilities (metadata, typed operations,
scoped grants, requests), cognition, snapshots (fork authority), security
and threat model (T14, T16, new T27–T29), architecture, README, changelog,
release notes, ADR-0012 and ADR-0013, and PLAN.md §8.10 status. The
unimplemented record_procedure internal step is removed from the
vocabulary; procedural memory is recorded when a plan completes.

 ### 8.9 Rollback
 
 Each unit is revertible. Migrations only add. Reverting cognition integration leaves inert tables; reverting the fork policy change restores inheritance. Capability grants are deleted with their table on down migration, which removes temporary authority rather than adding any.

+Defects found and fixed along the way: unwired UI approval and policy callbacks (aae312a), belief events published before commit (e7ebbf8), snapshot column discovery reading the wrong schema (a3caed7), and a stale step copy able to re-run a claimed step (e25d68f).
