T03: Cross-platform compilation verification on all three targets

Why: R006 requires code compiles on macOS, Linux, and Windows. This is the final proof that the transport abstraction works across all platforms.

Steps:

1. Run cargo check (current platform — macOS)
2. Run cargo check --target x86_64-unknown-linux-gnu
3. Run cargo check --target x86_64-pc-windows-msvc
4. If any target fails, fix conditional compilation issues:
   • Check #[cfg(unix)] / #[cfg(windows)] annotations are correct
   • Ensure transport module handles #[cfg(not(any(unix, windows)))] gracefully
   • Verify interprocess crate is still only in [target.'cfg(windows)'.dependencies]
   • Verify libc is still only in [target.'cfg(unix)'.dependencies]
5. Run cargo clippy on current platform for lint warnings

Constraints:

• All three targets must pass with zero errors
• Warnings should be minimized but non-blocking
• Do NOT modify Cargo.toml dependency structure unless required for compilation

Inputs

• src/transport/mod.rs
• src/daemon/server.rs
• src/daemon/mod.rs
• src/cli/daemon_cmd.rs
• src/cli/mod.rs
• Cargo.toml

Expected Output

• src/transport/mod.rs
• src/daemon/server.rs
• src/daemon/mod.rs
• Cargo.toml

Verification

cargo check && cargo check --target x86_64-unknown-linux-gnu && cargo check --target x86_64-pc-windows-msvc
