Janis 3750931251 feat: NCS-43 NNUE high-impact performance optimisations 
Implements three high-impact improvements from NCS-43:

1. Incremental L1 accumulator — L1 pre-activations are maintained
   per-ply on a stack and updated by column-add/subtract when pieces
   move, reducing L1 cost from O(768×1536) to O(pieces×1536) for root
   init and O(changed_pieces×1536) per node. Column-major weight
   transposition (l1WeightsT) makes each update sequential in memory.

2. Eval cache — a 256 K direct-mapped cache keyed by Zobrist hash
   skips the L2-L5 forward pass for positions seen during quiescence,
   where the same position often recurs across capture sequences.

3. Dynamic time allocation — NNUEBot now grants 1 500 ms in complex
   positions (> 30 legal moves) and 500 ms in nearly-terminal ones
   (< 5 moves), instead of a fixed 1 000 ms budget.

Accumulator hooks (initAccumulator, pushAccumulator, copyAccumulator,
evaluateAccumulator) are added to the Evaluation trait with no-op
defaults, so ClassicalBot and HybridBot are unaffected.

lq64 9ad11fb97a docs: NCS-36 Added an API spec for Now Chess (#25)
Build & Test (NowChessSystems) TeamCity build finished
Details 
## Summary
  - Adds `docs/api-spec.yaml` — a full OpenAPI 3.0.3 specification for the NowChess REST API
  - Endpoint paths follow the lichess `board/bot` split convention (`/api/board/game/...`)
    to leave room for a future bot API under `/api/bot/game/...`
  - Covers game lifecycle, move-making, draw handling, undo/redo,
    legal move introspection, and FEN/PGN import/export

  ## Endpoints
  - Game: POST /api/board/game, GET /{gameId}, GET /{gameId}/stream, POST /{gameId}/resign
  - Move: POST /{gameId}/move/{uci}, GET /{gameId}/moves, POST /{gameId}/undo, POST /{gameId}/redo
  - Draw: POST /{gameId}/draw/{action}
  - Import: POST /import/fen, POST /import/pgn
  - Export: GET /{gameId}/export/fen, GET /{gameId}/export/pgn

  ## Test plan
  - [ ] Open docs/api-spec.yaml in Swagger Editor (https://editor.swagger.io) — zero validation errors expected
  - [ ] Verify every endpoint maps to an existing GameEngine or RuleSet method
