refactor(transforms): replace magic numbers with named constants

[EmperorOrokuSaki]

Issue

Multiple magic numbers are hardcoded throughout the transforms crate, making the code less readable and maintainable.

Current State

Several magic numbers without clear meaning:

• 1024 in stack_noise.rs:49 (EVM stack limit)
• 64 in detection.rs:260 (auxdata scan window)
• 0x5b in detection.rs:333 (JUMPDEST opcode)
• 32_000 and 200 in obfuscate.rs:203 (gas calculation)

Proposed Solution

Replace with named constants:

const EVM_STACK_LIMIT: usize = 1024;
const AUXDATA_SCAN_WINDOW: usize = 64;
const JUMPDEST_OPCODE: u8 = 0x5b;
const BASE_GAS_COST: u64 = 32_000;
const GAS_PER_BYTE: u64 = 200;

Benefits

• Improved code readability
• Self-documenting code
• Easier to modify values in the future
• Reduced chance of typos

Files to Modify

• crates/transforms/src/stack_noise.rs
• crates/core/src/detection.rs
• crates/cli/src/commands/obfuscate.rs

Priority

Low - Code quality improvement
