Consolidate Tool Configuration Into a Single tools Property

>>> [!note] Migrated issue   Reported by: [robertoperuzzo](https://www.drupal.org/user/2661375) Related to !10 >>> <h3 id="summary-problem-motivation">Problem/Motivation</h3> Currently tool configuration is scattered across multiple entity properties — <code>enabled_tools</code>, <code>locked_tools</code>, and <code>tool_operations</code> — which makes the model harder to reason about, more error-prone and less type-safe. Maintaining parallel arrays introduces duplication, increases the chance of inconsistent state, and complicates validation, serialization, and change-tracking. Proposed consolidation: move every tool's configuration into a single <code>tools</code> property on the entity where each tool is represented by one complete configuration object/array: <pre><pre>[   'name' => 'tool_name',   'description' => 'Tool description',   'input_schema' => [...],        // MCP tool schema   // Configuration   'enabled' => true,   'locked' => false,   'operation' => 'read',          // read|write   // Locked definition (only if locked === true)   'locked_definition' => [     'name' => 'tool_name',     'description' => 'Tool description',     'input_schema' => [...],   ], ]</pre></pre>Consolidation creates a single source of truth and improves validation, maintainability, and type safety. It also prepares the codebase for properly typed DTOs/value objects. <h4 id="summary-steps-reproduce">Steps to reproduce</h4> <ol> <li>Create an entity with the current model using <code>enabled_tools</code>, <code>locked_tools</code> and <code>tool_operations</code>.</li> <li>Perform an operation requiring tool state validation (e.g. checking enabled/locked/operation mode).</li> <li>Observe that logic must reconcile multiple arrays, increasing risk of inconsistent state.</li> <li>Attempt to add or modify tool metadata; duplication across arrays complicates maintenance.</li> </ol> <h3 id="summary-proposed-resolution">Proposed resolution</h3> Replace the scattered arrays with a single <code>tools</code> list on the entity and introduce typed DTOs/Value Objects for clarity and type safety: <ul> <li>ToolCollection — collection wrapper for all tools.</li> <li>Tool — represents a single tool (config + metadata).</li> <li>InputSchema — representation of the tool’s input schema.</li> <li>LockDefinition — metadata snapshot when a tool is locked.</li> </ul> Example DTO API: <pre><pre>// ToolCollection get(string $name): ?Tool add(Tool $tool) remove(string $name) toArray()/fromArray() // Tool getName(), getDescription(), isEnabled(), isLocked(), getOperation() withEnabled(), withLocked(), withOperation(), withLockedDefinition() toArray()/fromArray()</pre></pre>Key behaviours: <ul> <li>When <code>locked === true</code>, a <code>locked_definition</code> must be present.</li> <li>Validation occurs in constructors/factories.</li> <li>Entity stores <code>tools</code> as a structured JSON or equivalent type.</li> </ul> <h3 id="summary-remaining-tasks">Remaining tasks</h3> <ol> <li>Design and implement DTOs (<code>Tool</code>, <code>ToolCollection</code>, <code>InputSchema</code>, <code>LockDefinition</code>).</li> <li>Create a migration script to consolidate old arrays into the new <code>tools</code> structure.</li> <li>Update entity schema: add <code>tools</code> property and deprecate old fields.</li> <li>Refactor logic to use DTO-based API instead of raw arrays.</li> <li>Write full validation and serialization tests.</li> <li>Update documentation and API references.</li> <li>Add getters/setters on the entity for <code>ToolCollection</code>.</li> </ol> <h3 id="summary-ui-changes">User interface changes</h3> Admin / configuration UI updates: <ul> <li>Replace multiple tool-related UI fields with a single consolidated tool configuration table.</li> <li>Display locked tools with read-only metadata pulled from <code>locked_definition</code>.</li> <li>Allow editing of a full tool object via a structured UI.</li> </ul> Migration UI: <ul> <li>Optional: provide a migration preview showing old vs new tool definitions.</li> </ul> <h3 id="summary-api-changes">API changes</h3> New entity methods: <ul> <li><code>getTools(): ToolCollection</code></li> <li><code>setTools(ToolCollection $tools)</code></li> <li><code>getTool(string $name): ?Tool</code></li> <li><code>hasTool(string $name): bool</code></li> </ul> Legacy methods become deprecated but remain readable for one release cycle. Example JSON shape: <pre><pre>{   "tools": [     {       "name": "tool_name",       "description": "Tool description",       "input_schema": { },       "enabled": true,       "locked": false,       "operation": "read",       "locked_definition": null     }   ] }</pre></pre><h3 id="summary-data-model-changes">Data model changes</h3> Introduce a single <code>tools</code> field (JSON/document/list-of-maps). Remove the following legacy fields: <ul> <li><code>enabled_tools</code></li> <li><code>locked_tools</code></li> <li><code>tool_operations</code></li> </ul> Migration strategy: <ol> <li>Read existing arrays and merge by tool name.</li> <li>Derive <code>enabled</code>, <code>locked</code>, and <code>operation</code> values.</li> <li>If <code>locked</code>, generate a proper <code>locked_definition</code>.</li> <li>Write consolidated structures into the new <code>tools</code> field.</li> <li>Deprecate old fields and remove after client migration period.</li> </ol>
