Add comprehensive database corruption recovery capabilities to bd doctor.
## Changes
### New Command Flags
- --force: Force repair mode that bypasses database validation
- --source: Choose source of truth (auto/jsonl/db) for recovery
### Enhanced Error Classification
Improved CheckDatabaseIntegrity() to detect and classify:
- Database locked errors (suggests killing processes, removing locks)
- Invalid SQLite files (suggests JSONL recovery with exact commands)
- Migration/validation failures (orphaned dependencies, etc.)
- Generic database errors (context-aware suggestions)
Each error type provides:
- Specific diagnosis
- Step-by-step recovery instructions
- Appropriate command examples with new flags
### Force Recovery Implementation
New DatabaseCorruptionRecoveryWithOptions() function:
- Bypasses database validation when --force is used
- Supports explicit source of truth selection
- Auto-detects best recovery path when source=auto
- Comprehensive rollback on failure
- Uses --force --no-git-history in import during force mode
### Integration
Updated fix orchestration to pass force and source flags to recovery.
## Usage Examples
```bash
# Unopenable database with validation errors
bd doctor --fix --force --source=jsonl
# Choose specific source of truth
bd doctor --fix --source=jsonl # Trust JSONL
bd doctor --fix --source=db # Trust database
bd doctor --fix --source=auto # Auto-detect (default)
# Force recovery with auto-detection
bd doctor --fix --force
```
## Problem Solved
Before: When database had validation errors (orphaned dependencies,
foreign key violations), all bd commands failed in a catch-22 situation.
Could not open database to fix database. Users had to manually delete
database files and reinit.
After: bd doctor --fix --force detects unopenable databases, provides
clear recovery steps, and forces rebuild from JSONL even when database
validation fails.
## Backward Compatibility
- All new flags are optional with safe defaults
- --source defaults to 'auto' (existing behavior)
- --force is opt-in only
- Existing bd doctor behavior unchanged when flags not used
- DatabaseCorruptionRecovery() still exists for compatibility
