feat: coded functions

[cristipufu]

Description

• Add agents entrypoint type alongside existing functions in uipath.json, allowing agent scripts to be registered
  separately from plain functions
• Breaking change: The runtime schema type field was previously hardcoded to "agent" for all entrypoints. It now
  correctly reflects the entrypoint type, "function" for entries in functions and "agent" for entries in agents.
  Existing functions entrypoints that were previously reported as "agent" will now be reported as "function".
• Update entrypoint discovery, resolution, and CLI warning messages to handle both functions and agents sections
• Bump version to 2.10.0

Breaking changes

Entrypoints declared under "functions" in uipath.json previously had their schema type set to "agent". They now correctly resolve to "function".

If you have entrypoints that should be treated as agents, move them from the "functions" section to the new "agents" section in uipath.json.
