05f04a90e0 Add generated schema headers (C++) and modules (TS)
Output of \`bun run codegen/generate.ts\` for the 8 mode schemas.
These files are checked in so consumers don't need bun on every
build, but they remain regenerable and byte-identical.

C++ (nisps/modes/generated/):
  schema_types.hpp + 8 <mode_id>_schema.hpp files. All compile
  cleanly with g++ -std=c++20 -Wall -Wextra -fsyntax-only -I nisps.

TS (playground/src/modes/generated/):
  types.ts + index.ts + 8 <mode_id>_schema.ts files. Type-check
  cleanly with tsc --strict.

e5bf2aa055 feat: nisps build + host test harness
CMakeLists.txt:
- Native host build by default; Emscripten-target detection plumbed but
  WASM emit deferred to stream 7 (playground build script).
- Header-only INTERFACE library `nisps_core`.
- Host test executable `nisps_core_tests` compiled with -Wall -Wextra
  -Werror -Wpedantic (Chris's rules: clean build is non-negotiable).

tests/cpp/test_helpers.hpp:
- Minimal NISPS_TEST / NISPS_EXPECT / NISPS_EXPECT_NEAR macros, no external
  deps. Rationale documented in-file: Catch2/doctest would add ~10MB and 30s
  for what is currently <100 LOC of test runtime.

22 unit tests covering FixedBuffer (5), RingBuffer (5), Rng (7), math (5).
All green; verified via `cmake --build nisps/build && ./nisps/build/nisps_core_tests`.

4f60fc8405 feat: nisps/core foundation — perf, types, concepts, buffers, rng, math
Greenfield C++20 core for the unified firmware+WASM rewrite (architecture.md
streams, meml-dn7). Header-only, platform-agnostic, no heap, no virtual
dispatch.

Components:
- perf.hpp        memory section + inlining macros, RP2040/RP2350-aware,
                  inert on host/Emscripten
- types.hpp       stereosample_t (mirrors firmware AudioDriver API),
                  sample_t/param_t aliases, DriverConfig negotiation struct
- concepts.hpp    MLEngine, AudioEngine, Mode (architecture §4.1-4.3)
- fixed_buffer.hpp  std::array-backed cursor; replaces std::vector in hot paths
- ring_buffer.hpp   SPSC lock-free FIFO, power-of-two capacity, atomic
                    head/tail; replaces pico/util/queue in core
- rng.hpp         xoshiro256+ with splitmix64 seeding, uniform/signed/
                  gaussian-via-3-uniforms (matches legacy MoveWeights shape)
- math.hpp        clamp01, fast_sigmoid (tanh-Padé, ~1.2% max err on [-6,6]),
                  exact_sigmoid, fast_exp, named Curve catalog (linear/exp/
                  log/square/sqrt/sigmoid/cubic) — TypeScript twin lives in
                  playground/src/output/curves.ts (stream 5)

Performance discipline (Chris's rules):
- No heap, no std::vector, no malloc/new in core
- All float literals carry .f suffix
- Memory section attrs syntactically present, inert on non-firmware builds
