Initialize LiDAR Harness for a project: detect typecheck/lint commands, establish baselines, classify task complexity.

Call this ONCE at the start of a session. Provide the user's task message for complexity classification.

Returns: session info with detected commands, complexity, and PGO readiness.

Classify a task as "simple" (question, explanation) or "complex" (implementation, refactor, fix).

Simple tasks skip PGO and review overhead entirely. Call before starting work.

Run incremental PGO (Pose Graph Optimization) typecheck/lint verification.

KEY CONCEPT: Only returns NEW errors not seen in previous calls. If you call it 10 times, each call only shows errors that appeared SINCE the last call. When it returns 0 new errors, the code compiles cleanly.

Use after each agent turn that modifies code to verify incrementally.

Run multi-perspective code review: security scan (secrets in git diff), correctness (uncommitted changes), style (lint results).

Call periodically (e.g. every 3rd turn) to catch issues the agent might miss.

Reset PGO baselines and shown-errors state for a fresh start.

Call when switching to a new task or after significant dependency changes.
