Lift bezier/ + bspline/ from Gangleri42 fork

First batch of code lifts: hardware-agnostic curve math packages.

- bezier/: cubic + quadratic Bezier curve representation +
  tessellation. Lifted verbatim from Gangleri42/seedhammer
  @ 0a3c63ef path bezier/. Stdlib only.

- bspline/: B-spline curves + an LP-based optimiser that finds the
  smallest engrave-stroke representation of a path. Lifted from
  Gangleri42/seedhammer @ 0a3c63ef path bspline/. Depends on
  bezier/ + gonum (BSD-3, brought in transitively).

Import paths rewritten from `seedhammer.com/X` to
`github.com/mineracks/seedhammer-v1-companion/X`. No other changes.

go build ./... and go test ./bezier/... ./bspline/... both clean.

Doc.go stubs updated to reflect LIFTED status with the source
commit pinned.

Deferred to next commit:
- backup/ (needs bc/fountain + bc/ur transitively for UR codes)
- font/{comfortaa,poppins,constant}/ (needs font/bitmap runtime)

Initial skeleton — Phase 1 scaffolding

A browser-based companion for SeedHammer v1 hardware. Three coordinated
PWAs (composer, emulator, combined-sim) plus an optional Android wrapper,
inspired by Gangleri42's SeedHammer II fork but retargeted to v1's
Pi-Zero / WaveShare / MarkingWay hardware.

What's in this commit:

- LICENSE: Unlicense (matching upstream)
- README.md: project overview + status + roadmap
- CREDITS.md: upstream provenance + pinned baseline SHAs
- docs/architecture/: five authoritative design docs (lifted from
  the prep work in mineracks-infrastructure):
  * BASELINES.md — pinned SHAs, license audit, path-mapping table
  * v1-engrave-spec.md — MarkingWay USB-serial wire protocol audit
  * v1-buttons-and-ui.md — GPIO map, UI screen flow, keyboard map
  * sh1e-spec.md — composer-to-Pi envelope format spec
  * seedsigner-reuse.md — Pyodide strategy + jumbo (SeedSigner+) support
- Go package skeleton with doc.go contracts:
  backup, bezier, bspline, engrave, engrave/wire, engrave/wire/sh1e,
  font (+ comfortaa, poppins, constant), gui, input, internal/golden,
  platform/v1
- cmd/ entrypoints with stub main(): composer, emulator, combined-sim,
  seedsigner-sim
- web/ static-shell skeleton
- go.mod (module github.com/mineracks/seedhammer-v1-companion, Go 1.22)
- go build ./... + go vet ./... both clean

Next: lift universal packages (backup, font, bezier, bspline) from
upstream seedhammer/seedhammer at v1.3.0 verbatim.
