fix: use bun-runner to find Bun on fresh install (#818)

Browse Source 
On fresh installations, smart-install.js installs Bun to ~/.bun/bin/bun
but Bun isn't in PATH until terminal restart. Subsequent hooks fail
because they try to run `bun ...` directly.

This fix introduces bun-runner.js - a Node.js script that finds Bun
in common install locations (not just PATH) and runs commands with it.
All hooks now use `node bun-runner.js ...` instead of `bun ...`.

The bun-runner checks:
- PATH (via which/where)
- ~/.bun/bin/bun (default install location)
- /usr/local/bin/bun
- /opt/homebrew/bin/bun (macOS Homebrew)
- /home/linuxbrew/.linuxbrew/bin/bun (Linuxbrew)
- Windows: %LOCALAPPDATA%\bun or fallback paths

Fixes #818
