corepack 0.34.2 (new formula)

[iMichka]

corepack was shipped by node at one point.
We removed the corepack formula to be consistent with that: #195770

Since node 25, corepack is not shipped anymore by node. See #252875

Thus, add the formula back ...

CC @chenrui333 as you removed it back then. Looks like we need to add corepack back.

Pull Request Overview

This PR restores the corepack formula to Homebrew after it was previously removed. Since Node.js version 25 no longer ships with corepack bundled, it needs to be available as a standalone formula. The PR adds the new corepack formula and updates conflict declarations in related formulas (yarn, pnpm, and hadoop) to prevent binary name collisions.

Key Changes:

• Adds new corepack formula (version 0.34.2) with proper dependencies and conflict declarations
• Removes the corepack → node rename mapping from formula_renames.json
• Updates yarn, pnpm, and hadoop formulas to declare conflicts with the new corepack formula
