[bug] clean install of macos results in build error

[ethanlee16]

describe the bug
Clean install of macOS does not compile successfully.

to reproduce

1. Follow the directions at https://docs.screenpi.pe/docs/getting-started#macos-installation to build screenpipe from source.
2. Observe that cargo build --release --features metal results in a build failure with the following error:

error[E0599]: no method named `len` found for type `i8` in the current scope
    --> /Users/ethan/.cargo/registry/src/index.crates.io-6f17d22bba15001f/sysinfo-0.31.4/src/unix/apple/macos/process.rs:432:53

     |                                                     ^^^
     |
help: there is a method `le` with a similar name, but with different arguments

     |
1196 |     fn le(&self, other: &Rhs) -> bool {
     |     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

expected behavior
build command should succeed

system info

• os: macos 15.1.1 (24B91)
• screenpipe version: 0.1.98

additional context
This may have happened due to a recent update to libc types for macOS released a couple hours ago in 0.2.165: rust-lang/libc#4062

I resolved this issue by setting libc to exactly 0.2.164 in screenpipe-vision:

screenpipe-vision/Cargo.toml

[target.'cfg(target_os = "macos")'.dependencies]
- libc = "0.2"
+ libc = "=0.2.164"
xcap = "0.0.13" 

[target.'cfg(target_os = "linux")'.dependencies]
- libc = "0.2"
+ libc = "=0.2.164"
xcap = "0.0.14"

This is related to sysinfo 0.31.4 getting pulled in by xcap, and the sysinfo issue is being tracked here: GuillaumeGomez/sysinfo#1392
