Update b2c-webdav skill with comprehensive log file reference

Added detailed log file documentation:
- Log file naming patterns (<type>-<hostname>-appserver-<date>.log)
- Custom log file types (customdebug, custominfo, customwarn, customerror, customfatal)
- Custom named log files (custom-<prefix>-<hostname>-appserver-<date>.log)
- System log file types (error, warn, jobs, quota, deprecation, etc.)
- Log retention and archive locations (log_archive/ for compressed logs)
- Security logs and import/export logs
- Common log query examples using grep

+## Log File Reference
+
+### Log File Naming Pattern
+
+Log files follow this naming pattern:
+```
+<type>-<hostname>-appserver-<date>.log
+```
+
+Example: `customerror-blade0-1-appserver-20240115.log`
+
+### Custom Log File Types
+
+Files generated by script logging (`dw.system.Logger`):
+
+| Log Type | Generated By | Default State |
+|----------|--------------|---------------|
+| `customdebug` | `Logger.debug()` / `log.debug()` | Disabled |
+| `custominfo` | `Logger.info()` / `log.info()` | Disabled |
+| `customwarn` | `Logger.warn()` / `log.warn()` | Always enabled |
+| `customerror` | `Logger.error()` / `log.error()` | Always enabled |
+| `customfatal` | `log.fatal()` | Always enabled |
+
+### Custom Named Log Files
+
+Created with `Logger.getLogger(prefix, category)`:
+```
+custom-<prefix>-<hostname>-appserver-<date>.log
+```
+
+Example: `custom-orderexport-blade0-1-appserver-20240115.log`
+
+```bash
+# list custom named log files
+b2c webdav ls --root=logs | grep "custom-orderexport"
+
+# download a custom named log
+b2c webdav get custom-orderexport-blade0-1-appserver-20240115.log --root=logs
+```
+
+### System Log File Types
+
+| Log Type | Description |
+|----------|-------------|
+| `error` | System errors in scripts, templates, platform |
+| `warn` | Lock status, slot warnings, servlet warnings |
+| `info` | System information |
+| `debug` | Debug information (when enabled) |
+| `fatal` | Critical system failures |
+| `api` | API problems and violations |
+| `deprecation` | Usage of deprecated APIs |
+| `jobs` | Job status information |
+| `staging` | Replication process information |
+| `quota` | Quota warnings and limit violations |
+| `sql` | SQL and replication issues |
+| `syslog` | API processing, staging, import/export |
+| `sysevent` | Appserver registration, cartridge logs |
+
+### Log Retention and Archives
+
+| Location | Retention |
+|----------|-----------|
+| `/Logs/` | Current logs (< 3 days old) |
+| `/Logs/log_archive/` | Compressed logs (3-30 days) |
+| Production/Staging | 30 days |
+| Security logs | 90 days |
+
+```bash
+# list current logs
+b2c webdav ls --root=logs
+
+# list archived (gzipped) logs
+b2c webdav ls log_archive --root=logs
+
+# download archived log
+b2c webdav get log_archive/customerror-blade0-1-appserver-20240112.log.gz --root=logs
+```
+
+### Security Logs
+
+Security logs track authentication events:
+
+```bash
+# list security logs
+b2c webdav ls --root=securitylogs
+
+# download security log
+b2c webdav get security-blade0-1-20240115.log --root=securitylogs -o - | grep "LOGIN"
+```
+
+### Import/Export Logs
+
+Located in IMPEX root under `/log/`:
+
+```bash
+# list import/export logs
+b2c webdav ls log --root=impex
+
+# download catalog import log
+b2c webdav get log/Catalog-Import-20240115.log --root=impex
+```
+
+### Common Log Queries
+
+```bash
+# find recent error logs
+b2c webdav ls --root=logs | grep customerror
+
+# search for specific order in error log
+b2c webdav get customerror-blade0-1-appserver-20240115.log --root=logs -o - | grep "ORD12345"
+
+# search for payment errors
+b2c webdav get customerror-blade0-1-appserver-20240115.log --root=logs -o - | grep -i "payment"
+
+# check job failures
+b2c webdav get jobs-blade0-1-appserver-20240115.log --root=logs -o - | grep -i "failed"
+
+# check quota warnings
+b2c webdav get quota-blade0-1-appserver-20240115.log --root=logs -o - | grep "exceeded"
+
+# check deprecated API usage
+b2c webdav get deprecation-blade0-1-appserver-20240115.log --root=logs
 ```
