core:services:helper: Migrate helper to secondary venv and update its dependencies

API calls can be validated at http://blueos.local:81/v1.0/docs

Summary by Sourcery

Migrate the helper service into the secondary Python virtual environment and align its configuration and dependencies with the updated workspace layout.

Bug Fixes:

• Prevent potential runtime issues in the helper service by ensuring optional metadata defaults to None.

Enhancements:

• Upgrade helper service dependencies (FastAPI, Pydantic, requests, uvicorn, BeautifulSoup, loguru, psutil, fastapi-versioning) to newer versions and refresh lockfiles.
• Adjust workspace and dependency wiring so the helper service is no longer part of the primary core environment and is instead managed under python-venv2.

Reviewer's Guide

Migrates the helper service from the primary core workspace into the secondary python-venv2 environment and refreshes its dependency stack (FastAPI, Pydantic, etc.), including lockfiles and startup wiring, with one minor model default tweak for compatibility.

File-Level Changes

Change	Details	Files
Upgrade helper service runtime dependencies to newer library versions.	Bump beautifulsoup4, fastapi, fastapi-versioning, loguru, psutil, pydantic, requests, and uvicorn to newer pinned versions in helper's pyproject configuration Keep helper marked as a non-installable package via tool.uv.package=false	core/services/helper/pyproject.toml
Move helper service from the primary core environment into python-venv2 and rewire workspace membership.	Remove helper from core/pyproject dependencies and workspace sources Exclude services/helper from the core workspace member glob so it is no longer managed by the primary environment Add helper as a dependency and workspace member in python-venv2/pyproject, alongside commonwealth, versionchooser, and kraken Update python-venv2 workspace members to include ../services/helper so uv resolves it in the secondary venv Regenerate uv.lock files for both core and python-venv2 to reflect the new environment layout and dependency graph Adjust start-blueos-core startup script wiring so helper runs under python-venv2 (details are in the regenerated script/lockfile)	core/pyproject.toml core/python-venv2/pyproject.toml core/python-venv2/uv.lock core/uv.lock core/start-blueos-core
Improve helper ServiceInfo model definition for compatibility with updated Pydantic.	Set a default value of None for the optional metadata field on ServiceInfo to ensure correct optional handling under Pydantic v2 and to avoid missing-field validation issues	core/services/helper/main.py

Hey - I've left some high level feedback:

• With the bump to FastAPI 0.125 and Pydantic 2.12, review helper service code for any Pydantic v1-style APIs (e.g., .dict(), .json(), Config classes, arbitrary_types_allowed) and FastAPI behaviors that changed (e.g., response_model handling, jsonable_encoder) to ensure they’re updated to the v2 patterns.
• Now that metadata on ServiceInfo is explicitly defaulted to None, verify any callers that relied on it being required or always present so they don’t break on None and adjust type hints or runtime checks accordingly.

## Overall Comments
- With the bump to FastAPI 0.125 and Pydantic 2.12, review helper service code for any Pydantic v1-style APIs (e.g., `.dict()`, `.json()`, `Config` classes, `arbitrary_types_allowed`) and FastAPI behaviors that changed (e.g., response_model handling, `jsonable_encoder`) to ensure they’re updated to the v2 patterns.
- Now that `metadata` on `ServiceInfo` is explicitly defaulted to `None`, verify any callers that relied on it being required or always present so they don’t break on `None` and adjust type hints or runtime checks accordingly.
