chore: bump Wayfinder Router to 1.0.0

[tcballard]

Summary

• bump the Wayfinder Router formula from the calendar-versioned prerelease to router-v1.0.0
• pin the verified GitHub source-archive SHA-256
• set version_scheme 1 so Homebrew compares the new SemVer line correctly

Verification

• downloaded the exact router-v1.0.0 source archive and independently verified SHA-256 d7ab09fde8193ce12f855a8de74870f1f929dd596991879ba028fd03b600e709
• installed the archive with Cargo using the formula's crate path
• passed the formula routing smoke expectations for schema v3 and the local recommendation
• git diff --check

Environment note

The current Linux runner does not provide Homebrew or Ruby, so brew audit and Ruby syntax checks remain CI/reviewer gates. No formula release or merge is performed by this pull request.
