Rename the project to FieldCraft

Crates fieldcraft-*, binaries fieldcraft and fieldcraft-cli, the .fieldcraft file (format tag
fieldcraft/1, manifest fieldcraft.json), FIELDCRAFT_* environment variables, the MCP server
name, egui widget ids (fc_*), the app icon document FieldCraft.icon and its generated family,
docs and licences. No compatibility shim: no files of the earlier name exist.

# Capability checklist (reference: Abaqus/CAE)
What an analyst does in a full CAE pre-processor, grouped by milestone, with ModelCraft's status.
What an analyst does in a full CAE pre-processor, grouped by milestone, with FieldCraft's status.
Scope comes from the public documentation of Abaqus/CAE and public analyst discussion,
described in our own words; nothing was taken from the product itself (AGENTS.md: no commercial

boundary conditions active in every step go to the initial state, and steps restate their
boundary conditions and loads with `OP=NEW` when the active set changes.

at least ten significant digits. Linear solids map full integration to `PSOLID` `TWO`/`THREE` +
`FULL`, hex20 reduced to `TWO` + `FULL`, hex8 incompatible modes to `BUBBLE`; one-point reduced
linear solids, hybrid solids, reduced-integration or one-point shells, body forces, gravity on part
of the model, orthotropic beams and rods, and orthotropic shells off planes of constant Z are
reported as unsupported. Static and frequency steps need separate decks (`deck.write` `steps`).
