docs: unbreak rustdoc CI (escape angle-bracket placeholders)

[EffortlessSteven]

Summary

Three doc comments were using <lane>, <path> and [options] unescaped, causing the strict-rustdoc CI gate (.github/workflows/docs.yml, RUSTDOCFLAGS="-D warnings") to fail with invalid-html-tags and broken-intra-doc-links errors. The failures were latent on main since 2026-05-15 because the workflow only triggers on crates/**/*.rs, Cargo.{toml,lock} and the workflow file itself — any push that doesn't touch a Rust file silently leaves docs red.

Files touched:

• crates/cli/src/commands/mod.rs — wrap <lane>/lane-init.json in backticks
• crates/tools/src/bin/validate_adr.rs — move usage / options into a fenced text block
• crates/tools/src/bin/generate_docs_index.rs — same treatment

No behavior change; documentation only.

Verification

RUSTDOCFLAGS="-D warnings" cargo doc --all-features --workspace \
  --no-deps --locked --exclude racing-wheel-ui
# -> Finished, no warnings/errors

cargo clippy -p wheelctl -p openracing-tools --all-targets --all-features
# -> clean

cargo fmt --all -- --check
# -> clean

Safety

Documentation-only change. No RT path, IPC, hardware, or signature code touched.

Migration Guide

To migrate these usages, replace:

• .temp_c() → .temperature_c
• .faults() → .fault_flags
• .wheel_angle_mdeg() → .wheel_angle_deg
• .wheel_speed_mrad_s() → .wheel_speed_rad_s

See Migration Patterns for detailed examples.
