helix-code-1.1.0-dev-0.0.3 — HelixLLM mode switch + HelixAgent bump

Dev release.

Added

• HelixLLM runtime mode switch. The shared HelixLLM accepts coder / claude mode parameter for mode-appropriate system prompts and token budgets.

Changed

• HelixAgent submodule pointer bumped — Zen provider default + generic provider fallback.

Fixed

• .gitignore covers scratchpad/ and .git-backups/ — 86 GB+ of build derivatives no longer pollute git status.

See CHANGELOG.md for full details.
