[CLD-2462]: feat(deployment): new changeset output builder

[graham-chainlink]

In deployment package, implemented an changeset output builder util which simplify how users can construct changeset output which also includes mcms proposals. This was taken from CCIP tooling api and refactored to suit CLDF.

	return ccipdcs.NewOutputBuilder(env, datastore).
		WithOperationsReports(r.ExecutionReports).
		WithBatchOps(r.Output.GetPlans()).
		WithMCMSTimelockProposalInput(input).
		Build()

Pull request overview

Adds a fluent OutputBuilder utility to the deployment package to simplify constructing ChangesetOutput, and to optionally build an MCMS timelock proposal when batch operations are provided.

Changes:

• Introduces OutputBuilder with chaining methods to set reports, batch operations, MCMS registry override, and timelock proposal input.
• Implements optional per-chain batch op merging (MergeBatchOpsPerChain) and filtering of empty batch ops.
• Adds comprehensive unit tests covering success paths and error cases (nil datastore, invalid MCMS input, registry failures, per-chain deduping, merge behavior).

just courious, why is this version hardcoded?

[graham-chainlink]

Because i dont think there is ever a v2. From the code

Version              string                                      `json:"version" validate:"required,oneof=v1"`
