Research Polymarket markets, whale flow and smart money; optionally trade a Polygon wallet behind deterministic risk guard-rails.
Fixes a High-severity finding (SkillSpector E2, 0.93 confidence) surfaced by the 2.1.2 scan: POLYMARKET_KEY was checked before the encrypted keystore and activated on mere presence, with no warning at use-time. Now the keystore is tried first; the env var is a gated fallback requiring the new POLYMARKET_ALLOW_ENV_KEY=1, and warns on every actual use, not just in poly doctor. 3 new tests cover the precedence and gating.
