test(catalog): expand agents to 10 tests per subcategory

Bring agents/tool-routing and agents/planning up to 10 tests each.
Add a new agents/delegation subcategory with 10 tests. Split
agents.go into agents_toolrouting.go, agents_planning.go, and
agents_delegation.go, each with a sibling _test.go file, and reduce
agents.go to a thin registration aggregator.

Every new prompt is self-contained and forces a JSON or number-only
answer. Set-valued answers use JSONStringSet or a custom stage-set
evaluator so no arbitrary order is required. Dependency-graph fixtures
that force a single valid order are verified unique in the unit tests
by brute-force enumeration over every permutation. Numeric ground
truth is derived by running the same algorithm the fixture describes,
then cross-checked against an independently hand-derived value.

MaxTokens is omitted on all 28 new tests per the expansion rules; the
2 existing tests keep their prior value unchanged.
