fix: platform-aware session hooks and auto-memory for Qwen Code

[btxbtxbtx]

Summary

v1.0.100 introduced session continuity (compact/resume) and auto-memory search, but these features were hardcoded to Claude Code conventions — Qwen Code users got no benefit. This PR makes the hook layer and auto-memory platform-aware.

Changes

1. hooks/session-helpers.mjs — Add QWEN_OPTS + detectPlatform()

• Added QWEN_OPTS with .qwen config dir, QWEN_PROJECT_DIR, QWEN_SESSION_ID
• Added detectPlatform() function that auto-detects the running platform from env vars

2. hooks/sessionstart.mjs — Platform-aware startup

• Uses detectPlatform() to get correct env vars and config paths
• Scans QWEN.md instead of CLAUDE.md when running under Qwen Code
• Uses QWEN_PROJECT_DIR / QWEN_PLUGIN_ROOT instead of hardcoded CLAUDE_*

3. hooks/precompact.mjs — Platform-aware config dir

• Uses detectPlatform() for correct resolveConfigDir() and getSessionDBPath()

4. hooks/posttooluse.mjs — Platform-aware session DB

• Uses detectPlatform() for correct getSessionDBPath() and getInputProjectDir()

5. src/search/auto-memory.ts — Scan both CLAUDE.md and QWEN.md

• Added memoryFileNames parameter (default: ["CLAUDE.md", "QWEN.md"])
• Scans both file types in project dir and config dir

6. src/server.ts — Adapter-aware configDir

• Uses _detectedAdapter.getSettingsPath() to derive config dir when adapter is available
• Falls back to CLAUDE_CONFIG_DIR / ~/.claude for unknown platforms

Test results

• qwen-code adapter: 22/22 pass
• search tests: 153/153 pass
• store tests: 110/110 pass
• No regressions
