fix: Respect allowedTools configuration in validTools array (#294)

The `disableTools: true` option was not fully respected - tool definitions
were correctly filtered from the system message, but the agentic loop still
accepted and executed tool calls because the `validTools` array was hardcoded
and didn't respect the `allowedTools` configuration.

Changes:
- Replace hardcoded `validTools` array with dynamic filtering using
  `allowedTools.isEnabled()` pattern (same as `getSystemMessage()`)
- Edit tools now require both `allowEdit` flag AND `allowedTools` permission
- Bash tool requires both `enableBash` flag AND `allowedTools` permission
- Delegate tool requires both `enableDelegate` flag AND `allowedTools` permission
- Add comprehensive tests to verify validTools respects allowedTools config

Fixes #293
