chaincfg: add own module, use v2
✓ Descriptive subject✓ Names a concrete action or component! No meaningful explanatory body
What changed, and why it matters
This commit is a routine Go module restructuring: it makes the chaincfg package its own versioned module (chaincfg/v2) and updates its internal imports to use versioned chainhash/v2 and wire/v2 modules. There are no code logic changes, no bug fixes, and no security-sensitive behavior changes visible in the diff.
Recommended action
No security action required. Treat as normal dependency/module maintenance. Consumers importing chaincfg should update to chaincfg/v2 when adopting the new module version.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff shows only import-path changes (chaincfg -> chaincfg/v2, chainhash -> chainhash/v2, wire -> wire/v2), README/doc updates, and the addition of a new go.mod/go.sum for the chaincfg/v2 module. No executable code semantics are modified. The replace directives in go.mod point to local paths for sibling modules that are not yet tagged, which is standard Go workspace/module development practice.
