ECC v1.8.0: Harness Performance Release

v1.8.0 shifts ECC from "config bundle" to a practical agent harness performance system: more reliable hooks, stronger eval/quality controls, and tighter parity across Claude Code, Cursor, OpenCode, and Codex (macOS app + CLI).

Reliability and Hook Fixes

• Fixed SessionStart root resolution (robust fallback when plugin root env is missing).
• Fixed empty/partial session summary behavior by moving summary persistence to the Stop lifecycle path where transcript payload exists.
• Added explicit hook controls:
• ECC_HOOK_PROFILE=minimal|standard|strict
• ECC_DISABLED_HOOKS=comma,separated,ids
• Replaced fragile inline one-liner hook commands with dedicated scripts for safer cross-platform behavior.
• Improved Windows path handling for doc-warning/whitelist logic.
• Hardened observer behavior for non-interactive environments to reduce hang risk.

Cross-Harness Parity

• Claude Code, Cursor, OpenCode, and Codex now share tighter behavior around hooks, commands, and skill execution semantics.
• OpenCode command mirrors added for the new harness command set.
• Codex config/docs alignment improved for both app and CLI workflows.

Compatibility Notes

• autonomous-loops is retained for compatibility in this release.
• continuous-agent-loop is now the canonical skill name.

Upgrade Path

1. Pull latest and reinstall/update ECC.
2. Run /harness-audit to baseline reliability and risk.
3. Use /quality-gate . --strict on active repos.
4. If needed, tune hooks with ECC_HOOK_PROFILE and ECC_DISABLED_HOOKS.
