feat(formation/templates): four new course templates + shared helpers

Browse source 
Adds the four templates called out in docs/teaching_order.md so the formation
pipeline can ratify more than just definitional ontologies:

* composed_relation — Layer 4.  Chains are the unit of mastery; each chain of
  length >= 2 emits a composed_relations entry with composition_kind
  (transitive | lifting), an inferred relation, and chain-break adversarial
  probes drawn from counters or canned.
* procedural — ordered state transitions; strict_linear_topo refuses
  branches, cycles, and disconnected components at render time.
  ordering_hints validated against the linear chain.  Canned violation
  probes for precondition_violation / step_skip / back_edge.
* falsification — counter-example-driven.  Counters move to Phase 2 paired
  with coherent alternatives drawn from relations sharing the same head.
  Unmatched counters surface in unmatched_counters; false-coherent probes
  emitted per pair.
* identity_anchor — Layer 1 seeding.  Concepts interpreted as identity axes
  ranked by ordering_hints; counters interpreted as override attempts;
  canned IDENTITY_OVERRIDE_PROBES always appended.

Common helpers extracted to formation/templates/_common.py: canonical
constants (MAX_VERSOR_CONDITION, RATIFICATION_GATES, PROMOTION_PATH,
IDENTITY_OVERRIDE_PROBES, NORMALIZATION_FORBIDDEN_SITES), deterministic
ordering (sorted_concepts/_counters/_hints, topo_sorted_relations,
strict_linear_topo), payload builders, geometric_dependencies,
maximal_chain_walks, adversarial_block, course_id, subject_payload,
substrate_invariants_payload, phase_5_payload.

formation/templates/__init__.py now dispatches via a lazy-import _REGISTRY
keyed by template_id; registered_template_ids() exposed for callers and
tests.  definition.py refactored to use _common verbatim — byte-stability
preserved (existing test_compose.py still passes; test_sha_stable_across_
subprocess unchanged).

Tests: 44 new tests across test_template_{composed_relation,procedural,
falsification,identity_anchor,registry}.py.  Each new template gets
determinism, paradigm-structure, error-handling, and cross-subprocess SHA
stability tests; registry test asserts the five known ids and that
identical inputs through different templates produce different SHAs.

Formation suite: 138 -> 182 passing.  cognition (121) and smoke (67)
suites unchanged.  ratify.py enforcement of the new paradigm-specific
gates (every_composed_relation_replayed, linear_order_strict, etc.)
remains a documented follow-up — templates declare the gates in their
phase_5 body so the ratifier extension is purely additive.

A template renders a :class:`ValidatedTripleSet` into a canonical course
YAML body (a JSON-shaped dict of strings/lists/dicts — no floats).
Templates are deterministic: same input -> same output bytes.
Lookups are by ``template_id``. Each template carries its own
``template_version``; bumping the version invalidates downstream
``course_sha256`` values, which is intentional.
Templates in this registry, by ordering-rule layer:
* ``definition`` — Layer 2. Every relation is a definitional edge.
* ``composed_relation`` — Layer 4. Chains are the unit of mastery.
* ``procedural`` — Layer 4. Ordered state transitions.
* ``falsification`` — counter-example-driven; supports any layer.
* ``identity_anchor`` — Layer 1. Identity axes and refusal probes.
See ``docs/teaching_order.md`` for the layer doctrine.

"""The ``composed_relation`` template — chains as the unit of mastery.
Layer 4 of the teaching order (see ``docs/teaching_order.md``). Where the
``definition`` template treats every relation as an independent edge, this
template treats *chains of relations* as first-class objects. Each maximal
chain of length >= 2 produces a ``composed_relation`` entry that names the
inferred relation the chain licenses, classifies the composition kind, and
ties back to the constituent edges by triple.
Composition kinds:
* ``transitive`` — every edge in the chain shares the same ``relation``
predicate (``A R B; B R C => A R C``).
* ``lifting`` — predicates differ but compose into a new asserted relation.
Phase 4 augments adversarial probes with one *chain-break* counter per
composed_relation (drawn from ``counters`` whose ``head`` matches the
chain's head and whose ``tail`` matches the chain's tail). If no
chain-break counter is provided, a canned probe is emitted so the
adversarial slot is never empty for a chain.

"""The ``falsification`` template — counter-example-driven mastery.
The unit of mastery is the rejected claim plus the coherent alternative.
Where ``definition`` makes ``relations`` load-bearing and ``counters``
adversarial, this template reverses the polarity: ``counters`` are the
primary content of Phase 2 and each counter must be paired with a
``coherent_alternative`` drawn from ``relations`` that share the same
``head``.
Pairing rule:
* A counter is *paired* if at least one relation has ``head == counter.head``.
The lexically-smallest such relation by ``(relation, tail)`` is its
coherent alternative.
* A counter with no matching relation is recorded under
``unmatched_counters`` in Phase 2. This is allowed (the template still
succeeds), but the ratifier should treat unmatched counters as a flag
for follow-up curation.
Phase 4 emits a *false-coherent* probe per pair: a near-miss that looks
like the alternative but is itself a counter (the same ``head`` with a
different ``tail`` — drawn from the remaining counters if available, else
a canned generic probe).

"""The ``identity_anchor`` template — Layer 1, identity seeding.
The course *is* the identity probe set. ``concepts`` are interpreted as
identity axes whose ``definition`` field carries the axis's behavioral
commitment (e.g. ``"Precision-first: weight accuracy over coverage"``).
``counters`` are interpreted as override attempts the system must refuse.
``relations`` are interpreted as compatibility constraints between axes
(``axis_a compatible_with axis_b``); these are optional.
This template is run first in any new domain so subsequent courses have
an anchored identity to ratify against. It hard-requires at least one
counter — an identity course with no override attempts is not an
identity-anchor course, it is a definition course, and the caller is
told to switch templates.
Axis priority is derived from ``ordering_hints``: a hint
``axis_a -> axis_b`` means ``axis_a`` ranks above ``axis_b``. Axes
unmentioned by any hint get appended in lex order after the ranked ones,
so output is fully deterministic even when hints under-specify.
