[plan] Type `SafeInputsMCPVersion` constant with the `Version` semantic type

[github-actions]

Objective

Add the Version type to the SafeInputsMCPVersion constant, which is inconsistently declared as an untyped string while all 20+ neighboring version constants are properly typed.

Context

Discussion #17885 (Typist - Go Type Consistency Analysis) identified this as an obvious oversight — every neighboring Version constant in pkg/constants/constants.go uses the Version semantic type except this one.

Location

File: pkg/constants/constants.go (around line 654)

// Current — untyped (inconsistent)
const SafeInputsMCPVersion = "1.0.0"

// Fixed — consistent with all other Version constants
const SafeInputsMCPVersion Version = "1.0.0"

Files to Modify

• pkg/constants/constants.go — add Version type to SafeInputsMCPVersion

Acceptance Criteria

• SafeInputsMCPVersion uses the Version type
• All usage sites compile correctly (the Version type has a String() method and is compatible with string operations)
• make build and make test-unit pass
• make fmt and make lint pass
