Update documentation for configuration file support and regex pattern matching

- Add configuration file support section in README and CI-CD docs
- Document --config-file option and lrm.json auto-discovery
- Add regex pattern matching examples for view command
- Update commands table with format support for all commands

+## Configuration File Support
+
+LRM supports configuration files to avoid repeating common options. Create a `lrm.json` file in your resource directory:
+
+```json
+{
+}
+```
+
+LRM will automatically discover and use `lrm.json` in the resource path, or you can specify a custom config file:
+
+```bash
+# Use auto-discovered lrm.json
+lrm validate --path ./Resources
+
+# Use custom config file
+lrm validate --config-file ./my-config.json --path ./Resources
+```
+
+In CI/CD workflows, you can commit your `lrm.json` to version control and all commands will use it automatically.

+### 7. Explore Keys by Namespace with Regex Patterns
+
+Use the `view` command with regex patterns to explore and document keys by namespace:
+
+```yaml
+- name: Document Error Messages
+  run: |
+    # Export all error message keys to JSON for documentation
+    lrm view "^Error\\..*" --regex --format json > error-messages.json
+
+- name: Document UI Labels
+  run: |
+    # Export all label and button keys
+    lrm view "^(Label|Button)\\." --regex --sort --format json > ui-elements.json
+
+- name: Verify Validation Messages
+  run: |
+    # Check that all validation keys are present
+    VALIDATION_KEYS=$(lrm view "Validation" --regex --format json | jq '.matchCount')
+    if [ "$VALIDATION_KEYS" -lt 10 ]; then
+      echo "Warning: Only $VALIDATION_KEYS validation keys found"
+      exit 1
+    fi
+```
+
+### 8. Generate Translation Reports by Category
+
+```yaml
+- name: Generate category-based translation reports

+**Description:** View details of a specific key or multiple keys matching a regex pattern across all languages.
 
 **Arguments:**
-- `<KEY>` - The key to view (required)
+- `<KEY>` - The key or regex pattern to view (required)
 
 **Options:**
 - `-p, --path <PATH>` - Resource folder path
+- `-c, --config-file <PATH>` - Path to configuration file
+- `-f, --format <FORMAT>` - Output format: `table` (default), `json`, or `simple`
+- `--regex` - Treat KEY as a regular expression pattern
 - `--show-comments` - Include comments in output
-- `--format <FORMAT>` - Output format: `table` (default), `json`, or `simple`
+- `--limit <COUNT>` - Maximum number of keys to display (default: 100, 0 for no limit)
+- `--no-limit` - Show all matches without limit (same as --limit 0)
+- `--sort` - Sort matched keys alphabetically
+
+**Modes:**
+- **Exact match (default):** View a single specific key

+- **Regex timeout:** 1-second limit prevents ReDoS attacks
+- **Default limit:** Shows first 100 matches to avoid overwhelming output
+- **Invalid pattern detection:** Clear error messages for malformed regex
+- **Backward compatible:** Exact match by default, regex is opt-in
+
+**Use Cases:**
+- **Namespace exploration:** View all keys in a namespace (e.g., `Error.*`)
+- **Pattern discovery:** Find keys by pattern without knowing exact names
+- **Documentation:** Generate translation reports for specific areas
+- **Validation:** Check translations for entire feature groups
+- **CI/CD integration:** Export specific key groups as JSON
