Address review feedback: versioned Homebrew formulas (node@22, node@20)
use keg-only paths where the stable symlink is at <prefix>/opt/<formula>/bin/node,
not <prefix>/bin/node. Updated resolveStableNodePath to:
1. Try <prefix>/opt/<formula>/bin/node first (works for both default + versioned)
2. Fall back to <prefix>/bin/node for the default "node" formula
3. Return the original Cellar path if neither stable path exists

When `openclaw gateway install` runs under Homebrew Node, `process.execPath`
resolves to the versioned Cellar path (e.g. /opt/homebrew/Cellar/node/25.7.0/bin/node).
This path breaks when Homebrew upgrades Node, silently killing the gateway daemon.
Resolve Cellar paths to the stable Homebrew symlink (/opt/homebrew/bin/node)
which Homebrew updates automatically during upgrades.

On macOS, `openclaw gateway install` hardcodes the system node
(/opt/homebrew/bin/node) in the launchd plist, ignoring the node from
version managers (fnm/nvm/volta). This causes the Gateway to run a
different node version than the user's shell environment.
Two fixes:
1. `resolvePreferredNodePath` now checks `process.execPath` first.
If the currently running node is a supported version, use it directly.
This respects the user's active version manager selection.
2. `buildMinimalServicePath` now includes version manager bin directories
on macOS (fnm, nvm, volta, pnpm, bun), matching the existing Linux
behavior.
