- home/lib/default.nix: add assertion for unknown profile names instead of
silently filtering them out; remove unused 'inherit (lib) optional'
- home/coding/agents/{opencode,pi}.nix: moved from home/features/coding/
to co-locate with agents.nix (eliminating cross-directory back-references)
- home/coding/agents/agents.nix: update imports to ./opencode.nix and ./pi.nix
- home/features/coding/: remove now-dead default.nix (nothing imported it)
