[WIP] Complete search routine extraction and clean up main.rs

[Copilot]

Coding agent has begun work on Complete search routine extraction and clean up main.rs and will replace this description as work progresses.

See problem context

Finish the refactor by moving all remaining search methods and evaluation from main.rs into board.rs. Specifically, extract:

• fn evaluate(&self) -> i32 including full piece-square tables and material evaluation code.
• fn negamax(&mut self, tt: &mut TranspositionTable, depth: u32, alpha: i32, beta: i32) -> i32 with alpha-beta, TT probing and storing, quiescence base case.
• fn quiesce(&mut self, tt: &mut TranspositionTable, alpha: i32, beta: i32) -> i32 including standing pat and tactical move generation.
• fn generate_tactical_moves(&mut self) -> Vec<Move> and its helper fn generate_pawn_tactical_moves.

After moving these, remove the corresponding methods from main.rs, and update main.rs to only declare modules:

mod types; mod zobrist; mod utils; mod board; mod perft;
use std::io::{self, BufRead, Write};
use std::time::{Duration, Instant};
use types::*; use zobrist::*; use utils::*; use board::Board;
fn main() { /* existing UCI loop unchanged */ }

Ensure cargo build passes with no logic changes.
