Fix publish workflow: matrix build for all packages; rename shared module; remove backward-compat re-exports

[Copilot]

The publish workflow only published the adk package, had a broken packages-dir, and hardcoded the Python version. Additionally, the shared module had an unnecessarily verbose name and adk carried redundant backward-compatibility re-export files.

Changes

• publish.yml

  • Refactored to a strategy.matrix over [shared, adk, msaf] with max-parallel: 1, eliminating the duplicated build/publish steps — each matrix job handles version-bump → build → publish for its package
  • python-version-file reads from adk/pyproject.toml
  • Explicit packages-dir: <pkg>/dist on every publish step

• copilot-setup-steps.yml

  • python-version: "3.14" replaced with python-version-file: "adk/pyproject.toml"

• shared/ module rename: agenticlayer_shared → agenticlayer

  • Renamed shared/agenticlayer_shared/ → shared/agenticlayer/ (namespace package, no __init__.py)
  • Renamed otel.py → _otel.py within shared to avoid a namespace conflict with adk/agenticlayer/otel.py
  • Updated shared/pyproject.toml packages to ["agenticlayer"]
  • All imports from agenticlayer_shared.* updated to agenticlayer.* (or agenticlayer._otel) across adk/, msaf/, and their tests

• adk/agenticlayer/ — removed backward-compat re-exports

  • Deleted pure re-export files: config.py, constants.py, loguru_config.py, otel_starlette.py, __init__.py
  • All consumers now import directly from the agenticlayer namespace

• adk/pyproject.toml and msaf/pyproject.toml

  • pytest pythonpath extended with "../shared" for namespace package resolution
  • msaf mypy config updated: namespace_packages = true, explicit_package_bases = true, mypy_path = [".", "../shared"]

• msaf/Makefile

  • mypy --no-incremental to avoid a mypy caching issue with transitive google namespace packages

<issue_description>Add a second agent framework to this sdk: https://github.com/microsoft/agent-framework

Use the Python API and implement the same SDK API as for ADK. Extract common logic to a new shared module, containing only framework independent code.</issue_description>

We do not care for backwards compatibility for now. There is only one client and we'll refactor that afterwards. Consider this for all files that re-export currently.

[Copilot]

Done in 72f1cdf. Deleted all pure re-export files from adk/agenticlayer/: config.py, constants.py, loguru_config.py, otel_starlette.py, and __init__.py. All consumers now import directly from agenticlayer.* (the renamed shared namespace).

Don't use a shared namespace. Use a sub package for the implementations instead.
