refactor(planner): delete the greedy optimizer (#807)

* refactor(planner): delete the greedy optimizer

The rqe-optimizer MILP replaces it. Removes candidate_gen, cost_model,
greedy, sketch_properties, constants, translator, label_set_facts,
pipeline, the profile-selecting cost loader and candidate-gen-dump.
Hint extraction moves into milp.rs, and asap-optimizer-cli is MILP-only
(--milp and the greedy flags are gone).
