Trait FileProvider 

pub trait FileProvider: Send + Sync {
    // Required methods
    fn get(&self, path: &str) -> Result<Vec<u8>>;
    fn exists(&self, path: &str) -> bool;
    fn glob(&self, pattern: &str) -> Result<Vec<FileEntry>>;

Trait for file access providers

This trait allows for different implementations:

• SandboxedFileProvider: Real filesystem access (sandboxed to pack root)
• MockFileProvider: In-memory files for testing
• ArchiveFileProvider: Read files from a tar.gz archive (future)

Required Methods

fn get(&self, path: &str) -> Result<Vec<u8>>

Read the contents of a file as bytes

fn exists(&self, path: &str) -> bool

Check if a file exists

fn glob(&self, pattern: &str) -> Result<Vec<FileEntry>>

List files matching a glob pattern

fn lines(&self, path: &str) -> Result<Vec<String>>

Read a file as lines

Provided Methods

fn get_string(&self, path: &str) -> Result<String>

Read the contents of a file as a string (UTF-8)
