docs: define 120-issue Stellar Wave dependency graph

[dDevAhmed]

Summary

Defines the contributor backlog structure before creating Wave issues.

Included

• 120 planned issue IDs (SW-001 → SW-120);
• explicit dependency graph by workstream;
• points/difficulty/priority/workstream taxonomy;
• required Stellar Wave issue-label format;
• protected/high-conflict sequencing rules;
• first-batch selection of 16 dependency-free, low-conflict issues;
• reserve dependency-free template documentation issues.

The graph deliberately sequences generator, process-supervisor, config, deploy, workflow/release, and cross-template surfaces to reduce contributor PR conflicts.

This PR creates no contributor issues itself; it freezes the plan first so issue creation can be audited against one source of truth.
