refactor: Relax two-framework rule and add skill boundary clarity

strategic-analysis: No longer mandates "always apply at least two
frameworks." For broad/high-stakes questions, two+ are still
recommended. For specific, well-defined questions, one applied
rigorously is preferred over two applied superficially.

proposal-development: Add cross-reference to client-deliverables
for engagement deliverables vs pre-engagement proposals.

engagement-setup: Add cross-reference to workshop-facilitation
for standalone facilitated sessions vs engagement launch.

 # Engagement Setup
 
-Take a consulting engagement from "we just won this work" to "the engagement is running." This covers five things that happen roughly in sequence but overlap in practice: transitioning from sales to delivery, planning the kickoff, mapping stakeholders, designing discovery, and establishing the operating rhythm.
+Take a consulting engagement from "we just won this work" to "the engagement is running." This covers the first weeks of a consulting engagement: transitioning from sales to delivery, planning the kickoff, mapping stakeholders, designing discovery, and establishing the operating rhythm. For designing standalone facilitated sessions later in the engagement (strategy offsites, innovation sprints), see workshop-facilitation.
 
 The goal is shared understanding and momentum, not a stack of templates. Every artifact here should earn its place by driving alignment or unblocking work.

 2. **Provide substantive analysis, not empty templates.** For each cell, give 2-3 sentences of reasoning with evidence.
 3. **Quantify wherever possible.** Use specific numbers, not vague ratings:
