fix: realign workflow advance semantics and phase labels with workflow.yaml

Audit findings 2.1 + 2.2 (high).

2.1 WorkflowBar's static phase list was fiction from F2 on (F2 "Schema
linking" vs memoria, F4 "SQL plan" vs schema_linking, …): every live
session showed the wrong phase name. Both maps now mirror
harness/workflow.yaml (F1 chiarimento … F8 datamart).

2.2 forceAdvance (6ee5bda) let reviewer_decide advance:true bypass the
phase gate on ANY phase, contradicting SKILL.md's "auto-advance only
empty F2 / skipped F6". reviewer_decide is back on advanceIfReady (exit-6
no-op) and tells the model to close via reviewer_confirm; forceAdvance
stays only where selection IS the approval by design: reviewer_schema_linking
(F4) and the F8 promotion close path. SKILL.md now names the three
self-closing gates (F3 rewrite_question, F4 schema-linking advance:true,
F8 memory_promote) so gate and skill state one contract.
