[r5n-86] [Hydra] update command

[deralaxo]

Summary

Adds the hydra update command to upgrade all runner binaries to the latest version. The command detects the current version from runner symlinks, downloads the latest release, and re-links all runners across all profiles — stopping and restarting any that were running. Also fixes a biome config issue where useSortedKeys was silently reordering positional arguments.

Changes

Features

• Add hydra update command — downloads latest runner version, re-links hardlinked bin/, symlinked externals/, and copied scripts for all runners across all profiles
• Extends RunnerProvider interface with currentVersion(id) and update(ids) methods
• GitHubRunnerProvider detects installed version from externals symlink path and handles binary replacement while preserving registration files

Bug Fixes

• Disable biome useSortedKeys assist — it was silently reordering object keys in positionals() and group() calls, breaking CLI argument order at runtime

Chores

• Lint pass with updated biome config (import sorting, line wrapping)
• Remove now-unnecessary biome-ignore comment in sisyphus version.ts
