Fix bd-160: Implement JSONL integrity validation and prevent export deduplication data loss

## Problem Export deduplication feature broke when JSONL and export_hashes diverged (e.g., after git pull/reset). This caused exports to skip issues that weren't actually in the file, leading to silent data loss. ## Solution 1. JSONL integrity validation before every export - Store JSONL file hash after export - Validate hash before export, clear export_hashes if mismatch - Automatically recovers from git operations changing JSONL 2. Clear export_hashes on all imports - Prevents stale hashes from causing future export failures - Import operations invalidate export_hashes state 3. Add Storage interface methods: - GetJSONLFileHash/SetJSONLFileHash for integrity tracking - ClearAllExportHashes for recovery ## Tests Added - TestJSONLIntegrityValidation: Unit tests for validation logic - TestImportClearsExportHashes: Verifies imports clear hashes - TestExportIntegrityAfterJSONLTruncation: Simulates git reset (would have caught bd-160) - TestExportIntegrityAfterJSONLDeletion: Tests recovery from file deletion - TestMultipleExportsStayConsistent: Tests repeated export integrity ## Follow-up Created bd-179 epic for remaining integration test gaps (multi-repo sync, daemon auto-sync, corruption recovery tests). Closes bd-160
