feat: fix examples

[Raezil]

Summary by cubic

Updated all examples to the new UTCP “manual with tools” schema so they work with v0.3.0. Switched to call_template_type and added allowed_communication_protocols; providers.json is now a v1.0 tools manual.

• Refactors

  • Replaced legacy "providers" and "manual_call_templates" with the v1.0 tools manual (tools + tool_call_template) across all examples.
  • Added allowed_communication_protocols at the manual level to enforce protocol use.
  • Upgraded examples/providers.json to a v1.0 manual: manual_version/utcp_version, info, tools with inputs/outputs and tool_call_template, plus tags and API key variable support.
  • Updated comments and startup logs to reference the tools manual.

• Migration

  • Inline configs: use a full manual (tools + tool_call_template) with call_template_type.
  • Manual files: use tools[] with tool_call_template; include manual_version 1.0.0 and utcp_version 0.3.0.
  • Provide allowed_communication_protocols at the manual level.
