docs: Update all README.md files across OpenSIN-Code repos to current state

[Delqhi]

Description

README files across the OpenSIN-Code organization are outdated. Many show old version numbers, missing features, or incorrect installation instructions.

Scope: All 45+ OpenSIN-Code repos need README audit

Known Issues (from deep scans)

Repo	Issue
SIN-Code-Bundle	README may not reflect v1.2.0 features (sin code hub, sin sckg, tests)
SIN-Code-SCKG-Tool	README likely shows v0.2.0, now v0.6.1 with GraphQL, dashboard, hybrid search
SIN-Code-Security-Bundle	README shows 5 tools, now 8 (added SAST, Secrets, SBOM)
SIN-Code-Discover/Execute/Map/Grasp/Scout/Harvest/Orchestrate	Version tags inconsistent (-codocs, -initial, -ceo-audit-v3)
SIN-Code-IBD/PoC/ADW/Oracle/EFM	Show v0.1.0, minimal READMEs (3 lines)
All Python tools	Missing AGENTS.md reference in README
Simone-MCP	README may not reflect v0.6.0 protocol fix
SIN-Browser-Tools	README may not list all 106 tools

Standard README Template (all repos should follow)

## Acceptance Criteria
- [ ] All 45+ repos have README matching template
- [ ] Version numbers match latest git tag
- [ ] Installation instructions work
- [ ] MCP integration documented
- [ ] CoDocs/AGENTS.md compliance noted
- [ ] Maturity badge shown (Production/MVP/Alpha/Spec)

## Priority
**MEDIUM** — Documentation debt; blocks onboarding and trust

SIN-Code README updated to v0.1.2 (76.6% coverage, 11 new test files) — see commits 9963830 (v0.1.2) and 7962b73 (v3.0.0 rename). Other repos in the org still have outdated READMEs — out of scope for this session, per-repo work needed.

Status (2026-06-12, post-v3.5.0)

Priority: LOW — housekeeping, 1-2h total across 12+ repos.

Current state

• ✅ SIN-Code/README.md rewritten for v3.5.0 (commit f09d2e2)
• ❌ 12 skill repos (Websearch, Scheduler, Goal-Mode, Grill-Me, Marketplace,
  Doc-Coauthoring, Context-Bridge, Honcho-Rollback, Frontend-Design,
  MCP-Server-Builder, Browser-Tools, +1)
• ❌ 6 ecosystem tool repos (SCKG, IBD, PoC, ADW, Oracle, EFM)
• ❌ SIN-Browser-Tools, Simone-MCP, SIN-Code-Orchestration
• ❌ SIN-Code-WebUI-v2 (separate repo, has its own README but should
  mention SIN-Code as the backend)
• ❌ SIN-Code-Container-Tool-Go, SIN-Code-SAST-Tool, SIN-Code-SBOM-Generator,
  SIN-Code-SCA-Tool-Go, SIN-Code-Secrets-Scanner (in-tree security tools)

Template

Each README should mention:

• One-sentence purpose
• Installation (pip install or brew install or git clone)
• Link to SIN-Code/AGENTS.md master blueprint
• Status badge: ACTIVE/ARCHIVED from ECOSYSTEM.md
• For MCP skills: link to sin-code skill install <name> and the registry

Cross-refs

• Sister-issue: chore: Add missing AGENTS.md to 6 repos (SCKG, IBD, PoC, ADW, Oracle, EFM) #40 (AGENTS.md propagation)
• ECOSYSTEM.md is the source of truth — README must reflect its status
• CI: ecosystem-sync.yml enforces registry alignment

Update (2026-06-12, post-v3.7.0)

v3.7.0 closed other sub-items. README propagation (4 priority repos) is
in v3.8.0 scope (#59).
