Limitcast 0.19.1: optimizer and Codex patch hardening

Limitcast 0.19.1 adds optional repository optimization alongside forecasting and subagent budgets. This patch fixes Codex code-mode patch normalization: JSON-escaped patch literals now preserve stable edited-file identity across changing patch bodies.

• Failure-loop detection, confirmed check guidance, reversible capability pruning and a bounded repository map.
• Optional asynchronous Codex-backed learning/judging with grounded outputs, three-session promotion, stale-turn rejection, bounded calls and actual usage receipts.
• Copilot CLI hooks and a Pi extension. The optional model backend currently requires Codex. Native signed-in Copilot and Pi checks completed with read-tool and session-event delivery.

Validation: 255 tests, six deterministic replay cases, real detached-worker learning/redirect checks, and CI on Linux/macOS with Node 20/22/24. The six-case judge comparison tied TokenEconomizer at 5/6; no overall superiority or net savings claim.
