chore: Add ACLProcessorContext state and scope management - BED-9236

[definitelynotagoblin]

Description

Apply ACL processor context changes from SpecterOps/SharpHoundCommon#309 to SharpHound Enterprise. Context scope is defined to exist at Job-lifetime.

This is a first iteration of what I hope to be a larger migration to other *Processors, LdapUtilities, and static caches at large.

Motivation and Context

https://specterops.atlassian.net/wiki/spaces/BE/pages/2297266214/Solving+Static+Caches+in+SharpHound

This PR addresses: BED-9236

How Has This Been Tested?

GOAD lab, two collections run back to back.
For each domain, "Building GUID cache" occurs once in each collection log.

Walkthrough

The PR adds ACLProcessorContext to BaseContext and IContext, routes ACL processor creation through it, updates the CommonLibs version, and scopes BaseContext disposal within StartCollection.

Changes

ACL processor context integration

Layer / File(s)	Summary
Context ownership and disposal src/BaseContext.cs, src/Client/Context.cs, Sharphound.csproj	BaseContext initializes and exposes ACLProcessorContext. IContext declares the property. BaseContext.Dispose now disposes the context once. CommonLibsVersion changes to 4.8.0-rc2.
Processor factory usage src/Producers/LdapProducer.cs, src/Runtime/ObjectProcessors.cs	Both components obtain ACLProcessor instances through ACLProcessorContext.CreateACLProcessor.
Collection context scope src/Sharphound.cs	StartCollection creates BaseContext with scoped disposal and assigns it to the IContext pipeline variable.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 1b622

This updates the CommonLibs dependency for ACL processor context integration. No current merge-blocking risk is identified.

Poem

A rabbit sees the context grow,
With processors in a tidy row.
The scope now closes, clean and bright,
ACL work follows one shared light.
Hop, hop—the pipeline runs just right.
