v0.6.0 - Catalog expansion (phase 2)

Catalog expansion, phase 2: seven new methods (now 47), and the rest of the candidate field honestly resolved.

• +7 frameworks (now 47). Four practitioner-grade: Role-Storming (generate ideas as someone else, to get past your own self-censorship), Morphological Analysis (lay a solution's choices out as a grid and recombine them), Pairwise Comparison (rank options head-to-head when you cannot score them on a scale), and Minimax Regret (choose under deep uncertainty by minimizing your worst-case regret). Three honest C-tier methods (conceptually strong, not yet study-backed): Three Horizons, Causal Layered Analysis, and Contradiction / Tension Mapping.
• Two recipes. Kepner-Tregoe and PDCA / A3 ship as workflow chains of existing skills rather than as new methods, because that is honestly what they are.
• Seventeen documented "no"s. The candidates that did not clear the bar - folded into a method that already covers them, or rejected on the merits - are each published in the Framework Library with their reasoning. The Library now holds 25 such dossiers, so "we considered it and said no" stays browsable.
• Honesty held at scale. Of 26 candidates researched and adversarially re-checked, only 7 became skills (a 73% fold/reject rate). Breadth never trumped the grade - the rejections are as much the product as the additions.
