Tough-scenarios task bank for Prompt Golf (v3).

Goal: scenarios where the *original* (verbose, hand-written) prompt that
naturally steers the target is 150-300 tokens long, but the MINIMUM
effective prompt is much shorter and non-obvious. The agent's job is to
find that compressed prompt — i.e. learn which fragments of the verbose
specification are load-bearing for the target model.

This file is the seed batch (10 scenarios — domain classifiers). The
remaining 42 will be added in later commits across:
  - Structured extraction
  - Format-strict generation
  - Persona + constraint
  - Multi-step reasoning
  - Adversarial / calibration

Why classifiers first: they exercise the existing `exact_label` scorer
deterministically, so we can validate the whole base→trained CSV
pipeline before investing in the fuzzier tasks.

Each scenario follows the existing TaskSpec contract from server/tasks.py
so it merges into _ALL_TASKS without code changes elsewhere.

# ============================================================================
# Structured extraction (10)
#
# Mostly use scorer="json_contains_fields" — expected is itself a tiny JSON
# dict; the scorer parses the output, finds the first JSON object, and checks
# each expected key/value (case-insensitive on string values, exact on
# numbers). This means the verbose description must steer the target to (a)
# emit ONLY a JSON object and (b) use the exact key names. Both are non-
# obvious to compress.
