v0.3.0 — LLM judge + pr-code-reviewer demo + 2-tier mode

[0.3.0] — 2026-05-29

Added

• LLM judge — new check kind llm_judge for prose-output skills. Calls Anthropic Messages API directly via curl with ANTHROPIC_API_KEY. Default claude-sonnet-4-6; configurable to claude-opus-4-7 via EVAL_LLM_JUDGE_MODEL or per-check judge_model. 3-sample majority voting (samples: N per check). Returns verdict: null with explicit reason when API key missing, curl fails, response unparseable, or majority null — never fabricates a verdict. (PR #9)
• pr-code-reviewer demo skill — second skill alongside omo-session-distiller. 3 prose cases exercising the llm_judge check kind: adversarial SQL injection (must flag), false-positive control trivial rename (must approve), and partial-failure billing risk (must flag). (PR #10)
• 2-tier mode — --mode={smoke|full|2tier}. smoke (cheap haiku + 1 sample) is default. full (sonnet-4-6 + 3 samples) is the canonical pass. 2tier runs smoke first, then re-runs only the FAILED cases with full. Trigger string 2tier-escalation for history transparency. (PR #11)

Fixed

• run.sh SCRIPT_DIR shadowing — lib/diff.sh reassigned the variable on source, breaking sibling-script resolution from run.sh. Now uses RUN_SCRIPT_DIR for run.sh-owned paths.

Verified

• 10 test suites green: all of v0.2.0's 8 + llm_judge_unit + twotier_mode.
