Python: refresh dev dependencies and validate runtime bounds (#6238)

eavanvalkenburg · Copilot · web-flow · commit 8091d052d817 · 2026-06-01T17:53:56.000Z
Updates third-party dev dependencies across the Python workspace and
validates that all runtime dependency bounds still hold at both ends.

Dev dependency bumps (root, lab, declarative, durabletask):
- uv 0.11.6 -&gt; 0.11.17, ruff 0.15.8 -&gt; 0.15.15,
  pytest-asyncio 1.3.0 -&gt; 1.4.0, mcp 1.27.0 -&gt; 1.27.2,
  azure-monitor-opentelemetry 1.8.7 -&gt; 1.8.8,
  poethepoet 0.42.1 -&gt; 0.46.0, prek 0.3.9 -&gt; 0.4.3,
  types-python-dateutil and types-PyYaml stub bumps.
- Transitive Dependabot items swept via lock: idna 3.11 -&gt; 3.17,
  pip 26.0.1 -&gt; 26.1.2.

Deliberately excluded:
- opentelemetry-sdk stays 1.40.0: azure-monitor-opentelemetry (incl.
  1.8.8) hard-pins opentelemetry-sdk==1.40.
- mypy stays 1.20.0 and pyright stays 1.1.408: the 2.1.0 / 1.1.409
  bumps introduce new diagnostics that fail type checking and need
  dedicated PRs.
- rich kept as a range: agentlightning (lab[lightning]) forces
  rich==13.9.4.

Code/formatting changes driven by the ruff upgrade:
- devui lifespan now uses try/finally so shutdown cleanup always runs
  (ruff RUF075).
- Removed unused TYPE_CHECKING imports in core and foundry flagged by
  ruff 0.15.15.
- Reapplied ruff 0.15.15 formatting to the files it changed.

Validation: validate-dependency-bounds-test "*" passes (31/31 lower +
31/31 upper); typing 62/62; lint 31/31; devui tests pass.
