fix(modules): Correct SQL staging directory structure for AzerothCore

Fixed critical bug in stage-module-sql.sh that prevented module SQL from
being applied by AzerothCore's native updater.

Problem:
- Script was stripping 'db_' prefix from directory names
- Created updates/world/ instead of updates/db_world/
- AzerothCore's dbimport couldn't find the SQL files
- Result: [1146] table doesn't exist errors on deployment

Solution:
- Preserve full database type name (db_world, db_auth, etc.)
- Stage SQL to correct AzerothCore directory structure
- Verified against AC source code conventions

Impact:
- Critical for Phase 1 module SQL refactor
- Enables proper SQL tracking in updates table
- Prevents module initialization failures

Testing:
- Verified correct path: updates/db_world/ (not updates/world/)
- Confirmed against AzerothCore source structure
- Documented in docs/BUGFIX_SQL_STAGING_PATH.md

+# Bug Fix: SQL Staging Path Incorrect
+
+**Date:** 2025-11-15
+**Status:** ✅ FIXED
+**Severity:** Critical (Prevented module SQL from being applied)
+
+---
+
+## Summary
+
+Fixed critical bug in `scripts/bash/stage-module-sql.sh` that prevented module SQL files from being staged in the correct AzerothCore directory structure, causing database schema errors and module failures.
+
+---
+
+## The Bug
+
+### Symptom
+Deployment failed with error:
+```
+[1146] Table 'acore_world.beastmaster_tames' doesn't exist
+Your database structure is not up to date.
+```
+
+### Root Cause
+**File:** `scripts/bash/stage-module-sql.sh`
+**Lines:** 259-261
+
+The script was incorrectly removing the `db_` prefix from database types when creating target directories:
+
+```bash
+# WRONG (before fix)
+local target_subdir="${current_db#db_}"  # Strips "db_" → "world"
+local target_dir="$acore_path/data/sql/updates/$target_subdir"
+# Result: /azerothcore/modules/mod-name/data/sql/updates/world/  ❌
+```
+
+**Problem:** AzerothCore's `dbimport` tool expects SQL in `updates/db_world/` not `updates/world/`
+
+### Impact
+- **All module SQL failed to apply** via AzerothCore's native updater
+- SQL files staged to wrong directory (`updates/world/` instead of `updates/db_world/`)
+- `dbimport` couldn't find the files
+- Modules requiring SQL failed to initialize
+- Database integrity checks failed on startup
+
+---
+
+## The Fix
+
+### Code Change
+**File:** `scripts/bash/stage-module-sql.sh`
+**Lines:** 259-261
+
+```bash
+# CORRECT (after fix)
+# AzerothCore expects db_world, db_auth, etc. (WITH db_ prefix)
+local target_dir="$acore_path/data/sql/updates/$current_db"
+# Result: /azerothcore/modules/mod-name/data/sql/updates/db_world/  ✅
+```
+
+### Verification
+AzerothCore source confirms the correct structure:
+```bash
+$ find local-storage/source -type d -name "db_world"
+local-storage/source/azerothcore-playerbots/data/sql/archive/db_world
+local-storage/source/azerothcore-playerbots/data/sql/updates/db_world  ← Correct!
+local-storage/source/azerothcore-playerbots/data/sql/base/db_world
+```
+
+---
+
+## Testing
+
+### Before Fix
+```bash
+$ docker exec ac-worldserver ls /azerothcore/modules/mod-npc-beastmaster/data/sql/updates/
+world/  ❌ Wrong directory name
+```
+
+### After Fix
+```bash
+$ docker exec ac-worldserver ls /azerothcore/modules/mod-npc-beastmaster/data/sql/updates/
+db_world/  ✅ Correct!
+
+$ ls /azerothcore/modules/mod-npc-beastmaster/data/sql/updates/db_world/
+20251115_22_1_mod-npc-beastmaster_beastmaster_tames.sql  ✅
+20251115_22_2_mod-npc-beastmaster_beastmaster_tames_inserts.sql  ✅
+```
+
+---
+
+## Why This Bug Existed
+
+The original implementation likely assumed AzerothCore used simple directory names (`world`, `auth`, `characters`) without the `db_` prefix. However, AzerothCore's actual schema uses:
+
+| Database Type | Directory Name |
+|--------------|----------------|
+| World | `db_world` (not `world`) |
+| Auth | `db_auth` (not `auth`) |
+| Characters | `db_characters` (not `characters`) |
+| Playerbots | `db_playerbots` (not `playerbots`) |
+
+The bug was introduced when adding support for multiple database types and attempting to "normalize" the names by stripping the prefix.
+
+---
+
+## Impact on Phase 1 Implementation
+
+This bug would have completely broken the Phase 1 module SQL refactor:
+
+- ✅ **Goal:** Use AzerothCore's native updater for module SQL
+- ❌ **Reality:** SQL staged to wrong location, updater couldn't find it
+- ❌ **Result:** Module SQL never applied, databases incomplete
+
+**Critical that we caught this before merging!**
+
+---
+
+## Lessons Learned
+
+1. **Verify directory structure** against source code, not assumptions
+2. **Test with real deployment** before considering feature complete
+3. **Check AzerothCore conventions** - they use `db_` prefixes everywhere
+4. **Integration testing is essential** - unit tests wouldn't have caught this
+
+---
+
+## Related Files
+
+- `scripts/bash/stage-module-sql.sh` - Fixed (lines 259-261)
+- `scripts/bash/manage-modules.sh` - Calls staging (working correctly)
+- `scripts/python/modules.py` - SQL discovery (uses `db_*` correctly)
+
+---
+
+## Commit
+
+**Fix:** Correct SQL staging directory structure for AzerothCore compatibility
+
+Details:
+- Fixed `stage-module-sql.sh` to preserve `db_` prefix in directory names
+- Changed from `updates/world/` to `updates/db_world/` (correct format)
+- Verified against AzerothCore source code directory structure
+- Prevents [1146] table doesn't exist errors on deployment
+
+**Type:** Bug Fix
+**Severity:** Critical
+**Impact:** Phase 1 implementation
+**Testing:** Code review + path verification
+
+---
+
+**Status:** ✅ Fixed and ready to commit
