rename: aldabra → aldabra (per Sulkta 2026-05-04)

Aldabra giant tortoise (Aldabrachelys gigantea) — endemic to the
Aldabra atoll, up to 250 kg, 150-year lifespan. Long-lived,
defended, slow but unstoppable. Better metaphor for the wallet
than 'aldabra' which was on-the-tin descriptive.

All renames in one pass:
- repo: Sulkta-Coop/aldabra → Sulkta-Coop/aldabra (via gitea API)
- workspace dir: aldabra → aldabra
- crate dirs: wallet-{core,chain,mcp} → aldabra-{core,chain,mcp}
- crate names + path imports in Cargo.toml workspace + each crate
- binary name: aldabra → aldabra
- README, ROADMAP, docs/architecture: all references swept
