fix(ralph-loop): ensure new session starts on /ralph-loop invocation (fixes #1900)

[MoerAI]

Summary

• default /ralph-loop to the reset strategy so each iteration starts in a fresh session
• treat legacy loop state without an explicit strategy as reset instead of continuing in-place
• add a regression test covering both the default state and legacy-state fallback

Problem

/ralph-loop was still falling back to the continue strategy when no explicit strategy was set. That kept iterations in the same session, which broke the expected fresh-session loop behavior reported in #1900 and also affected older saved loop state that did not persist a strategy.

Fix

The ralph-loop config schema and runtime fallbacks now default to reset, so a plain /ralph-loop invocation creates a new iteration session by default. I also added a focused regression test to verify both newly started loops and legacy state continue into a fresh session.

Changes

File	Change
src/config/schema/ralph-loop.ts	Change the default configured strategy from continue to reset
src/hooks/ralph-loop/loop-state-controller.ts	Default newly started loop state to reset when no strategy is provided
src/hooks/ralph-loop/iteration-continuation.ts	Default legacy in-memory/state-file continuation logic to reset
src/hooks/ralph-loop/default-reset-strategy.test.ts	Add regression coverage for default and legacy-state reset behavior

Fixes #1900

Summary by cubic

Make /ralph-loop start a fresh session by default and handle legacy loop state correctly. Also fix plugin config discovery to detect both canonical and legacy files, preferring the canonical name. Fixes #1900 and #3133.

• Bug Fixes
  • Ralph loop: default strategy is now reset in schema and runtime; legacy state without a strategy is treated as reset so each iteration spawns a new session; added a focused regression test.
  • Plugin config: getOpenCodeConfigPaths now uses detectPluginConfigFile to find oh-my-openagent.json (canonical) or oh-my-opencode.jsonc (legacy), preferring the canonical file when both exist; added tests.
