centra 8f94aee1fa Fix R8: Convert submodule gitlinks to regular directories
- Remove gitlinks (160000 mode) for chainfire, flaredb, iam
- Add workspace contents as regular tracked files
- Update flake.nix to use simple paths instead of builtins.fetchGit

This resolves the nix build failure where submodule directories
appeared empty in the nix store.

# Research: Distributed KVS Consistency Modes (003-kvs-consistency)
## Decisions
- **Consistency scope**: Namespace-level selection of strong or eventual consistency.
- *Rationale*: Different tenants/workloads can choose per requirement.
- *Alternatives considered*: Cluster-wide only (too rigid).
- **Eventual consistency conflict resolution**: Default LWW (last-write-wins); allow alternative policies via config.
- *Rationale*: Simple baseline with deterministic resolution; extensible for advanced policies.
- *Alternatives considered*: Version vectors/CRDT as default (more complex to operate by default).
## Open Questions
- None (resolved by spec clarifications).
