fix(ci): unbreak main — black 26.x reformat + canonical namespace markers

[neuron7xLab]

Why

main HEAD was red on two checks (run 27783397409):

• research-integrity-gate → black --check would reformat tools/physics_score.py
• Release coverage gate (90%) → test_namespace_integrity_has_no_violations failed (a real test failure, not a coverage drop)

Root cause

Recently-merged dependabot bumps raised CI to black 26.x / ruff 0.15 / mypy 2.1 / pytest 9. tools/physics_score.py (merged via #1220 under old black) is reformatted by new black — tool-version drift. The new canonical packages src/geosync/research/{,transformer/} (added by #1204) lacked the required __CANONICAL__ = True marker enforced by the architecture guard.

Fix

• black 26.x reformat tools/physics_score.py (long-tuple wrap; semantically identical)
• add __CANONICAL__ = True to the two new __init__.py

Verified locally with exact CI toolchain

black --check (research-integrity paths) 258 unchanged; ruff clean; mypy --strict clean; namespace test 0 violations; commit-acceptor needs no new acceptor (edits to already-accepted files).

Known latent debt (deliberately separate)

The black bump leaves 6 more reformat-pending files, 2 in protected paths (execution/, core/). They fail no current gate and warrant a dedicated formatting PR with protected-path review — not a hotfix.
