<issue_title>[Feature] Enterprise-grade DI Mutation Safety: Deterministic Registration Plans, Contract Guarantees, and Auditable Container Changes (Insert/Append/Merge/Replace)</issue_title>
<issue_description>### Problem statement

ExperimentFramework swaps implementations in IServiceCollection to route calls through trials (proxies/mediators) and support experimentation. This is powerful, but DI mutation is a high-risk surface:

Service registration graphs can be complex (multi-registration with IEnumerable<T>, open generics, factories, decorators, TryAdd patterns).
A single incorrect replacement can create runtime failures, subtle behavior changes, or performance regressions.
Enterprises need determinism, validation, traceability, and provable safety guarantees with minimal overhead.

We need a comprehensive, globally consistent service registration system that:

Produces a deterministic, previewable registration plan before applying changes
Validates strict contract invariants (lifetimes, assignability, open generic constraints, disposal semantics, etc.)
Supports multi-registration semantics: insert / append / merge / replace
Emits traceable, auditable diagnostics (structured logs + optional persistence sink)
Introduces minimal overhead (startup-time analysis; runtime dispatch remains fast)

Goals

Global consistency: every mutation is expressed as a canonical “patch operation” applied to the original IServiceCollection.
Safety: prevent unsafe swaps by default; offer strict/lenient modes.
Traceability: every change produces an audit record and can be correlated to trials and runtime activity.
Compatibility: works with standard Microsoft DI semantics, including multi-registration (IEnumerable<T>), while remaining congruent with the existing fluent + YAML DSL. ([GitHub][1])
Minimal overhead: analysis occurs once at startup; runtime overhead is bounded and measurable.

Non-goals

Replacing the DI container itself (Autofac, Lamar, etc.). We target Microsoft.Extensions.DependencyInjection first.
Perfect static proof of all runtime behaviors (factories can execute arbitrary code). We focus on robust invariants + runtime-safe defaults.

Proposed design

A) Introduce a first-class “Registration Plan” pipeline

Concepts

ServiceGraphSnapshot: immutable snapshot of original descriptors (pre-mutation)
RegistrationPlan: ordered list of patch operations + validation results
ServiceGraphPatchOperation: canonical operations (Insert / Append / Merge / Replace) with explicit match rules
RegistrationPlanReport: human-readable + JSON output (for build artifacts / support tickets)

Flow

Capture snapshot of IServiceCollection
Build plan from ExperimentFramework config (fluent/YAML)
Validate plan (invariants)
Apply plan (mutate IServiceCollection)
Emit report + audit events
Optionally “dry run” (no mutation) for pre-prod validation

B) Canonical patch operations (multi-registration supported)

Operations

Replace: replace matched descriptor(s) with proxy/router descriptor(s)
Insert: insert descriptor before a matched one (preserve downstream ordering)
Append: add descriptor after the matched one(s)
Merge: merge multiple matches into one router/aggregate descriptor that preserves IEnumerable<T> semantics

Key requirement
All operations must define:

match predicate (by service type, implementation type, lifetime, key/name tags, assembly, etc.)
deterministic ordering rules
explicit result cardinality expectations (exactly one match / allow many / allow none)
rollback strategy if validation fails

C) Contract + safety invariants (the “guarantees”)

Validation rules (examples)

Assignability: replacement implementation/proxy must be assignable to service type
Lifetime safety: prevent injecting scoped into singleton via swap; detect and fail fast
Factory preservation: if original uses ImplementationFactory, either preserve factory or wrap with defined semantics
Open generic correctness: validate generic arity + constraints; avoid invalid open generic registrations
Disposal semantics: ensure disposables remain disposed correctly; avoid capturing scoped disposables in singletons
Multi-registration invariants: preserve ordering rules; avoid accidental collapsing of registrations unless explicitly requested via Merge
Idempotency: applying ExperimentFramework twice should not double-wrap or drift the graph

Modes

ValidationMode.Strict (default for enterprise): any unsafe condition fails startup with a clear report
ValidationMode.Warn: logs warnings, proceeds
ValidationMode.Off: for advanced scenarios only (still emits report)

D) Tra...

@copilot Implementation needs complete integration with existing service collection wireup, either native or opt-in. We need to ensure nothing in this is stubbed, partially completed, or left up to future implementors. This needs to be a feature-complete implementation that's ready to start using for existing users with nothing more than a version update (and optionally an opt in, perhaps via package reference or similar).

Complete integration implemented in commit 0fcb63e.

What's Changed:

Registration safety is now enabled by default in AddExperimentFramework()
Zero breaking changes - existing code works without modification
Fully integrated with native service collection wireup
Opt-out available via builder.DisableRegistrationSafety()

New Fluent API Methods:

EnableRegistrationSafety() / DisableRegistrationSafety()
WithRegistrationValidationMode(ValidationMode.Strict|Warn|Off)
WithDefaultMultiRegistrationBehavior(MultiRegistrationBehavior)
EmitRegistrationReport() - optional detailed logging

How It Works:
When users call services.AddExperimentFramework(builder), the framework automatically:

Captures service collection snapshot
Builds & validates registration plan
Executes with automatic rollback on failure
Throws clear exceptions if validation fails

No stubs, no placeholders - fully feature-complete and ready for immediate use.

All tests passing: 97/97 (18 new service registration tests + 79 existing integration tests)
