Add personas and jobs to be done to vision system

The vision system now guides defining WHO we build for and WHAT they're
trying to achieve before jumping into goals and issues.

Updated vision-management skill:
- New vision.md structure with Personas and Jobs to Be Done sections
- Guidance for defining good personas (specific, characterized, limited)
- Guidance for jobs to be done (outcome-focused, in their voice, pain-aware)
- Milestones now tied to personas and jobs with structured descriptions
- Issue alignment checks persona/job fit before milestone fit

Updated vision command:
- Guides through persona and JTBD definition when creating vision
- Output format shows personas and jobs prominently
- Guidelines emphasize traceability to personas

Updated plan-issues command:
- Identifies persona and job before breaking down work
- Plan presentation includes For/Job/Supports context
- Flags misalignment with persona/job, not just goals

-2. **Understand the feature**: Analyze what "$1" involves
-3. **Explore the codebase** if needed to understand context
-4. **Break down** into discrete, actionable issues:
+1. **Check vision context**: If `vision.md` exists, read it to understand personas, jobs to be done, and goals
+2. **Identify persona**: Which persona does "$1" serve?
+3. **Identify job**: Which job to be done does this enable?
+4. **Understand the feature**: Analyze what "$1" involves
+5. **Explore the codebase** if needed to understand context
+6. **Break down** into discrete, actionable issues:
    - Each issue should be independently completable
    - Clear dependencies between issues
    - Appropriate scope (not too big, not too small)

    ## Proposed Issues for: $1
 
-   Vision Alignment: Supports [Goal N: description]
+   For: [Persona name]
+   Job: "[Job to be done this enables]"
+   Supports: [Milestone/Goal name]
 
    1. [Title] - Brief description
       Dependencies: none
-      Supports: Goal N
 
    2. [Title] - Brief description
       Dependencies: #1
-      Supports: Goal N
 
    3. [Title] - Brief description
       Dependencies: #1, #2
-      Supports: Goal N
    ```
 
-   If the feature doesn't align with any vision goal, note this and ask if:
-   - The vision should be updated to include this as a goal
+   If the feature doesn't align with any persona/job/goal, note this and ask if:
+   - A new persona or job should be added to the vision
+   - A new milestone should be created
    - This should be added as a non-goal
    - Proceed anyway (with justification)
