fix(ctl): drop unused tabled derive features

[bkearns]

Removes unused tabled derive/macros/assert features from ferrosa-ctl and keeps only the std runtime API used by Builder and Style.

This removes tabled_derive, proc-macro-error2, and proc-macro-error-attr2 from the resolved graph, eliminating the stable release future-incompatibility warning without suppression.

TDD:

• RED: resolved feature graph contained tabled_derive and proc-macro-error2; stable release run 33142489229 emitted the future-incompatibility warning on macOS and Linux.
• GREEN: dependency-feature regression passes; cargo test -p ferrosa-ctl passes 299 tests; Clippy -D warnings and release build report zero warnings; fmt and diff checks pass.

Independent verification: PASS, no blockers.
