feat(guardrails): consume uipath-platform 0.2.9 for BYOG evaluation

[valentinabojan]

What changed?

Bumps the uipath-platform floor to 0.2.9 so Bring-Your-Own-Guardrail (BYOG) guardrails are evaluated correctly at runtime.

A BYOG guardrail is persisted as a BuiltInValidatorGuardrail with the "byo" sentinel validatorType and a byoValidatorName referencing the connector-backed configuration. uipath-platform 0.2.9 exposes byo_validator_name as a typed field and forwards it in the guardrail validation request; earlier versions dropped it, so the service could not resolve the configuration.

• pyproject.toml — uipath-platform>=0.2.5 → >=0.2.9; version 0.14.6 → 0.14.7.
• uv.lock — regenerated (uipath-platform 0.2.9).
• Regression tests confirming a "byo" built-in validator guardrail:
  • maps through build_guardrails_with_actions unchanged, preserving byo_validator_name
  • is not dropped by the stage filter (runs in every stage its scope runs)

Why

The runtime already passes the guardrail object straight through to evaluate_guardrail, so no source change is needed here — only the dependency floor so the forwarding is guaranteed present. With this bump, BYOG guardrails execute end-to-end.

Notes

Requires the platform change in UiPath/uipath-python#1810 (merged, released as uipath-platform 0.2.9).

All guardrail tests pass (279); ruff clean.

Pull request overview

This PR updates uipath-langchain to require uipath-platform>=0.2.9 so Bring-Your-Own-Guardrail (BYOG) built-in validator guardrails retain and forward byo_validator_name during evaluation, and adds regression tests to ensure BYOG guardrails are not altered or stage-filtered incorrectly.

Changes:

• Bumped dependency floor: uipath-platform>=0.2.5 → >=0.2.9 and package version 0.14.6 → 0.14.7.
• Regenerated uv.lock to reflect uipath-platform==0.2.9.
• Added tests validating BYOG guardrails preserve byo_validator_name, have actions mapped correctly, and are not dropped by stage filtering.
