Struct Node 

#[repr(C)]
pub struct Node {
    pub kind: u16,
    pub flags: u16,
    pub pos: u32,
    pub end: u32,
    pub data_index: u32,
}

A thin 16-byte node header for cache-efficient AST storage.

Layout (16 bytes total):

• kind: 2 bytes (SyntaxKind value, supports 0-65535)
• flags: 2 bytes (packed NodeFlags)
• pos: 4 bytes (start position in source)
• end: 4 bytes (end position in source)
• data_index: 4 bytes (index into type-specific pool, u32::MAX = no data)

Fields

kind: u16

SyntaxKind value (u16 to support extended kinds up to 400+)

flags: u16

Packed node flags (subset of NodeFlags that fits in u16)

pos: u32

Start position in source (character index)

end: u32

End position in source (character index)

data_index: u32

Index into the type-specific storage pool (u32::MAX = no data)
