fix: keep dev services in the user home

[version-1]

Keep the development service runtime in the user home

Summary

Make build-tq-dev place the managed services in the same ~/.tasq-dev home resolved by the dev build profile.

主な変更点:

• Build the three development services into ~/.tasq-dev/system/bin.
• Keep the dev profile so tqdev update remains disabled.
• Remove the unnecessary workspace-specific default-home override.

やったこと

• Simplified the home-resolution implementation back to its profile-based behavior.
• Quoted development runtime paths so HOME values containing spaces work correctly.

動作確認

• go test ./internal/config ./internal/cli/tq
• make -n build-tq-dev
• make -n HOME='/tmp/review home' build-tq-dev
• git diff --check

レビュー & 動作確認 チェックリスト

• Home consistency - tqdev config resolves ~/.tasq-dev and services are built below the same home.
• Update guard - the embedded dev profile keeps tqdev update unavailable.
• Shell-safe paths - build-tq-dev works when HOME has spaces.

推奨テスト計画:

1. Run make build-tq-dev.
2. Confirm service binaries exist in ~/.tasq-dev/system/bin.
3. Run ./tqdev service start after freeing the local ports.
