PR-02 Workspace Init, Registry, and Identity Foundation

Domain Owner: docs/packer

Briefing

Implement the packer-owned workspace control model and registry authority in prometeu-packer.

This PR turns the identity and workspace rules into executable code.

Objective

Deliver init_workspace, registry load/store, identity allocation, and asset-root resolution as the stable foundation for all later packer operations.

Dependencies

Scope

implement init_workspace
create and validate assets/.prometeu/index.json
implement monotonic asset_id allocation and persisted allocator state
model asset_uuid allocation and persistence
implement root resolution utilities used by future read/write operations
define structural registry errors and missing-root behavior

Non-Goals

no asset.json semantic validation beyond what registry ownership requires
no Studio adapter yet
no build artifacts yet

Execution Method

Implement packer-owned registry models and codecs.
Add workspace bootstrap behavior for missing control directories.
Enforce identity invariants around asset_id, asset_uuid, and root uniqueness.
Expose internal services for lookup by asset_id, asset_uuid, and root path.

Acceptance Criteria

workspace initialization creates the minimum control structure deterministically
registry state round-trips without losing allocator data
duplicate or ambiguous identity-bearing entries fail clearly
relocation can later update root location without changing identity fields

Validation

unit tests for registry round-trip and allocator monotonicity
unit tests for duplicate-root and malformed-registry failures
workspace-init fixture test

Affected Artifacts

prometeu-packer/**
assets/.prometeu/index.json contract implementation
