docs: fix rustdoc guides rendering on docs.rs (#955)

## Summary

- Add `[package.metadata.docs.rs]` with `all-features = true` so
feature-gated guide modules (`python_guide`, `logging_guide`) render on
docs.rs
- Fix Guides section in crate docs: add missing `live_mounts_guide`,
convert plain backticks to `[`link brackets`]` for clickable links

## Test plan

- [x] `cargo doc --all-features --no-deps` builds cleanly
- [x] All 6 guide links render correctly in generated HTML
- [x] `cargo test --all-features` passes
- [x] `cargo fmt --check` clean
- [x] `cargo clippy --all-targets --all-features -- -D warnings` clean
