chore(deps): drop unused tracing dependency

[senamakel]

Summary

Found by the cross-repo dependency audit in tinyhumansai/openhuman#6353 (pnpm dep:audit, tinyanalyzer-driven) and verified by grep against this tree at main. Manifest and lockfile only; no source changes.

• tinyskills: drop tracing — declared through the workspace but never referenced, so the workspace entry goes too. tracing and its three support crates leave the build graph.

Related issue

None.

API or behavior changes

None.

Validation

Commands actually run, with their outcome:

• cargo fmt --all -- --check — clean
• cargo clippy --workspace --all-targets --all-features -- -D warnings — clean
• cargo check --workspace --all-targets --all-features — clean
• cargo test --workspace --all-features — 26 passed, 0 failed

Tests

None added: dependency removal is verified by the build, not by a test.

Documentation

Not needed; no public surface changed.

Checklist

• The change is focused on one logical change
• No new #[allow(...)], #[ignore], or relaxed lints
• No secrets, tokens, or .env contents in the diff or the description

Summary by CodeRabbit

• Chores
  • Removed an unused internal dependency from the project configuration.
