refactor(okf): remove the OKF import, tier-1 ontology and concept sidecar -- code, tests, migrations, registrations

Owner ruling 2026-09-10 (ADR-0011 on main): OKF is not part of the solution
and is removed entirely, leaving no remnant, in preparation for a semantic
layer. Evidence in receipts/okf-removal-inventory-2026-09-10.md: no serving
path read any of it, 0/2,033 imported concepts citation-bound, the ontology
moved fused recall by +0.00, value gates never reached.

agent-session-tools: 12 modules deleted (concept_cli, concept_live,
concept_schema, concepts, okf_import, ontology, ontology_live, plus the
sidecar-only authorization, projection, safe_fs, winddown and recall
seams) and 18 test files; migrations v48/v49 and their registration
removed, CURRENT_VERSION back to 47 (what main ships); the
memory_winddown and memory_recall MCP tools removed so the tool set equals
main's; live_ontology/live_concepts markers removed from both pyproject
files. Ten files whose whole branch diff was OKF were restored to the
MERGE BASE (not main's current version -- restoring to main would have
imported main's newer work; caught and corrected during the lane's own
audit). recall.py was memory_recall's engine (PR #18 drop-half, d573133):
deleted rather than kept as a second session_search.

studyloop: check_ontology_freshness and its doctor registration removed
(_doctor.py and doctor/harness.py now match main); test_doctor_ontology.py
deleted. scripts/b4_recall_acceptance.py deleted (existed only to run the
v49 migration and import_okf); pin_poc_set.py docstring retargeted.

Kept, because they are not OKF: the learning-memory package and its
claims/evidence store; studyloop's learning tier (history/concepts.py,
learning/concept_quality.py, get_concept_context -- identical on main).

Gates on the worktree: ruff check clean, 727 files formatted, pyright
0/0/0; agent-session-tools 1,691 passed / 0 failed; studyloop reds equal
the pinned environment set plus two expected on a branch that predates
main's Stage 3 fix. Finish line: git grep for
okf|ontolog|concept_sidecar|context_concept|memory_winddown|memory_recall
over packages/ returns nothing.
