Add parent_id support to ExecuteToolScope and InferenceScope

[Copilot]

Extends parent span linking (from #164) to ExecuteToolScope and InferenceScope, enabling W3C Trace Context linking for tool execution and inference spans.

Changes

• ExecuteToolScope: Added optional parent_id parameter to start() and __init__()
• InferenceScope: Added optional parent_id parameter to start() and __init__()
• Both pass parent_id to base class OpenTelemetryScope for context propagation
• Added unit tests for parent span linking verification

Usage

parent_id = "00-{trace_id}-{span_id}-01"

with ExecuteToolScope.start(details, agent_details, tenant_details, parent_id=parent_id):
    ...

with InferenceScope.start(details, agent_details, tenant_details, parent_id=parent_id):
    ...

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Pull request overview

Extends existing W3C Trace Context parent span linking to ExecuteToolScope and InferenceScope by adding an optional parent_id parameter and propagating it into OpenTelemetryScope so spans can be created under an upstream parent context.

Changes:

• Added optional parent_id argument to ExecuteToolScope.start()/__init__() and passed it to OpenTelemetryScope.
• Added optional parent_id argument to InferenceScope.start()/__init__() and passed it to OpenTelemetryScope.
• Added unit tests asserting spans inherit the parent trace/span IDs when parent_id is provided.
