Add ideating-with-bdd for collaborative discovery and formulation of
behaviour. Update testing-with-gocuke-and-gherkin to focus on
automation.

Separates concerns:
- ideating-with-bdd: Discovery, brainstorming, requirements gathering
- testing-with-gocuke-and-gherkin: Automation, running tests, TDD

Document X-At and X-In headers for delayed notifications with examples
for both duration-based (X-In) and absolute time (X-At) scheduling.

Add notifying-through-ntfy skill to the list and update token stats.

Add commit categorization into three types:
- Feature branch representation (drop and re-pick)
- Already merged upstream (drop without re-picking)
- Personal-only (keep as-is)

Includes detection of merged upstream commits via git log --grep, and
explicit user categorization for ambiguous commits.

Adds guidance on crafting effective rumilo queries, emphasizing scope
and coupling considerations. Includes a comparison of overloaded vs
sequenced queries, with examples showing how to break down complex
research tasks into focused calls.

Sends push notifications via ntfy.sh when the user explicitly asks to be
notified. Includes curl examples in SKILL.md and alternative HTTP client
references (ht, httpie, wget, python, nodejs) for environments where
curl is unavailable.

Convert skill descriptions from declarative to imperative form. Add
references to tools and projects mentioned throughout the descriptions.
Improve clarity and conciseness across all 21 skills.

Update cloning.md to reflect that wt no longer automatically pushes
after clone.

Add new skill for generating git tag annotations with formatted-tag CLI.

Also update formatting-commits skill to reference git-format tool and
regenerate token stats in README.

Change default skills directory from ~/.config/crush/skills to
~/.config/agents/skills across Makefile and documentation. This makes the
path more generic and accommodates multiple agents that use this location
(Crush, Octofriend, Shelley, and Amp). Also adds documentation about tested
agents and updates the agent directories table to reflect current
configurations.

Restructure the fork rebase workflow to use a break after dropping stale
commits, enabling clean re-picking of feature branches before personal
commits are replayed.

- Rename Step 5 to clarify the drop+break pattern with sed command
- Add new Step 7 for continuing the rebase after re-picks
- Add section on handling bulk mechanical changes (renames, formatting)
- Add explicit warning to never skip commits during conflicts
- Fix anchor link reference to match new section name

Very much a WIP, that's why I haven't listed it yet.

wt init now copies untracked/ignored files to the worktree before
cleanup.
