Fix NixOS integration: separate package building from OS builds

Problem: Calling bild.run inside NixOS configs triggered IFD during
OS evaluation. ANSI escape codes from bild broke JSON parsing in Nix
sandbox, causing build failures.

Root cause: bild.run uses IFD (Import From Derivation) which runs
bild --plan during Nix evaluation. When this happened inside NixOS
service definitions, it ran recursively and bild output ANSI codes
that corrupted the JSON analysis output.

Solution: Two-phase architecture + NO_COLOR support

1. Biz/Packages.nix: Pre-builds all packages outside NixOS context
2. Biz.nix: Accepts packages as function argument (default:
Packages.nix) 3. Omni/Bild.nix: Sets NO_COLOR=1 in analysis
derivation 4. Omni/Log/Terminal.hs: Respects NO_COLOR env var
5. Omni/Log/Terminal.hs: Skip getTerminalSize when NO_COLOR set
to avoid
   escape code output
6. Omni/Log/Concurrent.hs: Skip line initialization without ANSI
support

Now NixOS builds succeed: - Package IFD happens once at top level -
No recursive builds during service evaluation - Clean JSON output
from bild --plan in Nix sandbox - NixOS configs reference pre-analyzed
packages

Changes: - Add Biz/Packages.nix - standalone package builder - Update
Biz.nix to accept packages argument - Update Biz/Dragons/Analysis.nix
to use Packages.nix - Remove Biz/Targets.nix (replaced by
Packages.nix) - Add NO_COLOR support throughout logging stack -
Fix ANSI.getTerminalSize outputting escape codes when NO_COLOR set
