[rush-daemon][WS2.3] Add warm engine component factory

[mojaza]

Summary

Adds the next reviewable WS2.3 increment for microsoft#5897: an opt-in factory that adapts a real, explicitly shaped all-project Rush engine into the warm WorkspaceSession lifecycle.

Depends on microsoft#5936. Tracks PBI 3216018.

Details

• Requires the command owner to provide a real all-project IOperationGraph, RushSession, refreshable IInputsSnapshot, and explicit phase/plugin shape.
• Validates graph ownership, all-project coverage, and declared operation phases rather than constructing a placeholder graph.
• Reconciles retained headless invalidations against refreshed input snapshots, maps path-specific changes to graph operations, and conservatively invalidates the full graph for unknown changes or reconciliation races.
• Serializes reconciliation and owns deterministic graph abort, runner closure, and component cleanup.
• Exposes the engine shape and reconciliation result through the existing WorkspaceSession seam while preserving the standalone daemon's current protocol behavior.
• Remains opt-in/dead-code-safe; normal Rush CLI behavior is unchanged.

A command-independent plugin/phase graph shape and per-iteration runner lifetime are still blocked by open microsoft#5895. This PR therefore does not duplicate PhasedScriptAction internals, construct a fake graph, or add phased request routing.
