Epic: rebrand pi-dev-loops to dev-loops and make it agent-harness-agnostic

[mfittko]

Scope

This epic owns the overall rebrand of pi-dev-loops to dev-loops and making the runtime agent-harness-agnostic. Implementation details are owned by the sub-issues below.

Phase	Sub-issue	Owns	Excludes
1	#764	Root package rename	Pi abstraction, core package handling
2	#765	Pi-specific coupling abstraction	Package rename, core package handling
3	#766	Core package handling	Rename, Pi abstraction
4	#767	npm publish pipeline and release	Code changes, migration guide
5	#768	Documentation rebrand	Code changes, migration guide
6	#769	Consumer migration guide and shims	Code changes, docs site rebrand

This issue owns overall epic coordination and final acceptance. It does NOT own implementation details owned by sub-issues (#764–#769).

Acceptance criteria

• The six execution slices are created, linked, and ordered as sub-issues of this epic.
• Each sub-issue has independent AC/DoD and a clear scope boundary.
• The sub-issue tree passes dev-loops refine verify.
• npm install dev-loops succeeds in a fresh project.
• npx dev-loops --help works without Pi-specific context.
• Existing Pi consumers have a documented migration path.

Definition of done

• All sub-issues are closed and their changes are merged.
• Final npm run verify and dev-loops refine verify pass on the completed tree.

Non-goals

• Rewriting the entire orchestration logic.
• Dropping Pi support.
• Duplicating the ordered child list in the epic body beyond the phase scope table above.
