Reasoning-expanded sibling of Fabliq-8B-Agent-FromBase. Adds general + deep reasoning (WithinUs + Helio) on top of the FromBase agentic foundation. Mirrors Fabliq-8B-Agent-Reasoning but for the FromBase ablation lineage.

🔬 Why this variant?

Two parallel lineages, both end with reasoning expansion:

Lineage	Phase-1	Phase-2
ToolBench line	`Fabliq-8B-Agent` (ToolBench → Fable-5)	`Fabliq-8B-Agent-Reasoning`
FromBase line (this)	`Fabliq-8B-Agent-FromBase` (base → Fable-5)	`Fabliq-8B-Agent-FromBase-Reasoning` (this)

Comparing the two Phase-2 endpoints answers: does ToolBench foundation matter for the final reasoning model, or is Fable-5 + reasoning enough?
