docs(@projects/@magic-civilization): 🛤️ p3-25 — record Phase-0 projection increments + blueprint link

Re-scope p3-25's view-completeness as Phase 0 of the owner's full UI-pure-view
migration (blueprint: designs/p3-rail1-ui-pure-view-migration-design.md). Log
the two landed increments (unit movement+posture 568e43084, golden age 0d501a3d7)
and the deferred bench-model gaps (XP, culture_stored, building_queues,
placed_buildings → Phase-1 SOT flip).

+Phase-0 increments landed (each `view_json`-additive, mc-player-api green):
+- [x] **Unit movement + tactical posture** (77a018e0f) — `project_units` stubbed
+  `movement_left/max=0`, `sentry=false`, `promotion_available=false` despite the bench `MapUnit`
+  carrying the data; fixed to read `movement_remaining`/`base_moves`/`is_sentrying`/

+- [x] **Golden Age → HUD** (f64ef19ba) — `ResourceView.golden_age_active/turns`.
+- Deferred (real bench-model gaps, → Phase 1 SOT flip, not fabricated): unit `experience`/XP,
