chore(objectives): fix Game-1 owner integrity + flesh out underground (g2-12) cluster
Game-1 dashboard fix: reassign 5 objectives off specialist-agent names
onto valid team-leads so objectives-report.py regenerates (it aborts on
any owner lacking a .project/team-leads/<owner>.md identity):
p1-61 game-data->terraformer, p1-57 game-systems->envoy,
p2-73/p2-60/p2-74 godot-engine|godot-ui->wireguard.
Underground (Game 2, stays OOS): decompose g2-12 umbrella into 8 ordered
phase objectives g2-12a..h (data model+save, worldgen, excavation, cross-
layer movement+pathfinding, per-layer fog, collapse, layer UI, AI
awareness); g2-11 blocked_by tightened to [g2-12a, g2-12c].
Dashboard regenerated: 319 objectives, README.md + objectives.json.
