This change simplifies recently touched skill scripts by removing
duplicated repo-root discovery code, promoting shared root lookup to a
public API, and tightening small readability issues without changing
behavior. It keeps script semantics intact while making cross-skill
reuse explicit.
- **Shared API cleanup (`.github/skills/shared/z3db.py`)**
- Promote `_find_repo_root` to public `find_repo_root`.
- Add `require_repo_root()` for scripts that should fail-fast when root
discovery fails.
- Update library usage docstring to expose both helpers.
- Replace adjacent SQL string literals in `log()` with a single literal.
- **Deduplicate memory-safety root lookup
(`.github/skills/memory-safety/scripts/memory_safety.py`)**
- Remove local `find_repo_root()` implementation.
- Import and use shared `require_repo_root()` from `z3db`.
- **Simplify static-analysis label selection
(`.github/skills/static-analysis/scripts/static_analysis.py`)**
- Replace two-step label assignment with a single expression:
- `label = f["type"] or f["category"]`
```python
# before
label = f["category"]
if f["type"]:
label = f["type"]
# after
label = f["type"] or f["category"]
```

Each step in every SKILL.md now carries labeled Action, Expectation,
and Result blocks so the agent can mechanically execute, verify, and
branch at each stage. Format chosen after comparing three variants
(indented blocks, inline keywords, tables) on a prove-validity
simulation; indented blocks scored highest on routing completeness
and checkability.

Introduce .github/skills/ with solve, prove, optimize, simplify,
encode, explain, benchmark, memory-safety, static-analysis, and
deeptest skills. Each skill follows a SKILL.md + scripts/ pattern
with Python scripts backed by a shared SQLite logging library
(z3db.py). Two orchestrator agents (z3-solver, z3-verifier) route
requests to the appropriate skills.
