Roadmap after 0.1.0

[joshlarssen]

Goal

Track the first post-0.1.0 improvements for behave-toolkit in one public roadmap issue.

Candidate next steps

• add step search and discovery helpers for large suites
• polish release/publication guidance for maintainers
• keep growing copy-paste examples in the public docs
• document the supported Python and Behave version matrix

Notes

This issue should stay intentionally short and point to concrete follow-up issues rather than becoming a giant design document.
