Create `docs/mainnet-launch-checklist.md`

[Nursca]

Description
The roadmap lists mainnet as a near-term goal. A checklist that tracks every requirement before mainnet launch — security audit, test coverage, documentation, contract upgradability — prevents premature or incomplete deployment.

Requirements and context

• Categories: Security (audit complete, coverage thresholds met, fuzz tests run), Contracts (upgrade path tested, multi-sig admin configured), Infrastructure (indexer deployed, monitoring configured), Documentation (all guides complete), Community (CONTRIBUTING, SECURITY, CHANGELOG up to date)
• Each item: description, owner, status, and link to the relevant issue or PR
• Update automatically when referenced issues are closed (via GitHub Actions)
• Include a signed-off-by section for core maintainers

Suggested execution

git checkout -b docs/mainnet-checklist

• Create docs/mainnet-launch-checklist.md
• Link each checklist item to the relevant GitHub issue
• Link prominently from org root README.md

Example commit message
docs: create mainnet launch checklist with per-item issue links
