fix: use *-CONTEXT.md glob for filename variants

Standardize on *-CONTEXT.md glob pattern to match files like
03-CONTEXT.md across all workflows.

Files updated:
- commands/gsd/plan-phase.md
- commands/gsd/research-phase.md
- get-shit-done/workflows/discuss-phase.md
- get-shit-done/workflows/resume-project.md

Closes #219

 ```bash

 If missing, suggest discuss-phase before plan. If exists, offer plan directly.
