Split oversized modules along domain seams

Every source file is now under 500 lines. Task prompt construction
moves from task-execution-service into task-prompts; goal assignee
resolution moves from organization-service into goal-kickoff; the
shared command types become a domain-structured shared/commands
directory with unchanged import paths; the provider adapter contract
types move to provider-adapter-contract, re-exported through
provider-adapters so callers keep a single public surface.
