feat(kyberforge): replace write-skill with spec-compliant skill-write and add skill-audit

Rewrote the skill authoring factory skill from scratch against the agentskills.io
specification. Renamed write-skill → skill-write (name now matches directory per spec).

skill-write:
- Full scaffold via new-skill.sh (annotated templates for SKILL.md, README.md,
  scripts/, references/, assets/)
- validate.sh checks all spec constraints deterministically (name format/length,
  description length, placeholder detection, line count, script rules)
- SKILL.md body includes description rules, body discipline, patterns, and scripts
  guidance with "why" rationale throughout
- Templates usable standalone by agents and humans

skill-audit:
- Structural validation (via validate.sh) + seven qualitative dimensions
- Produces PASS/FAIL/SUGGESTION punch list with per-FAIL fix proposals
- Report-only: does not apply fixes

+# scripts/
+
+Executable code bundled with this skill. Agents run scripts in this directory
+to perform repeatable operations rather than reinventing the logic each run.
+
+## When to add a script
+
+Add a script when agents independently reinvent the same logic across runs —
+building the same parser, chart, or validation routine from scratch each time.
+Bundle it here once, tested and reliable.
+
+## Script requirements (agentskills.io)
+
+Scripts must be designed for non-interactive, agentic execution:
+
+- **No interactive prompts** — agents run in non-interactive shells.
+  Accept all input via flags, env vars, or stdin. A script that blocks on
+  TTY input hangs indefinitely.
+- **Expose `--help`** — this is how agents learn your script's interface.
+  Keep the output concise; it enters the agent's context window.
+- **Structured output** — write data (JSON, CSV, TSV) to stdout.
+  Write progress, warnings, and diagnostics to stderr.
+- **Idempotent** — prefer "create if not exists" over "create and fail on
+  duplicate". Agents may retry on failure.
+- **Meaningful exit codes** — `0` for success, non-zero for failure.
+  Use distinct codes for different failure types; document them in `--help`.
+- **Dry-run support** — add `--dry-run` for destructive operations.
+
+## Self-contained scripts
+
+Bundle dependencies inline so the agent can run the script with a single command.
+
+Python (PEP 723 + uv):
+```python
+# /// script
+# dependencies = ["requests>=2.31,<3"]
+# requires-python = ">=3.11"
+# ///
+import requests
+```
+```bash
+uv run scripts/my-script.py
+```
+
+## If no scripts are needed
+
+Delete this README and the `scripts/` directory entirely.
