`waza dev` scores a SKILL.md file's frontmatter against heuristics and
suggests improvements. It's basically equivalent to the `sensei` CLI.
Closes #32, closes #33, closes #35

### What it does

`waza dev [skill-path]` reads a SKILL.md, scores its frontmatter for
compliance (trigger phrases, anti-triggers, routing clarity, description
length, token budget), and walks the user through improvements one at a
time. In `--auto` mode it applies all suggestions without prompting.

**Scoring levels** (Low → Medium → Medium-High → High) are determined by
the presence of:
- Trigger phrases (`USE FOR:`)
- Anti-trigger phrases (`DO NOT USE FOR:`)
- Routing clarity markers (`INVOKES:`, `**WORKFLOW SKILL**`, etc.)

### Example output

```
── Iteration 1/5 ──────────────────────────────────────────

Skill: skill-creator
Score: Low
Tokens: 4522
Description: 226 chars
Triggers: 0
Anti-triggers: 0

Issues:
  ⚠️ SKILL.md is 4522 tokens (soft limit 500)

📝 Suggested improvement (triggers):
────────────────────────────────────────
USE FOR: skill-creator, about skills, core principles, quick start, advanced features.
────────────────────────────────────────
Apply this improvement? [y/N]y

  Verified: score is now Medium

── Iteration 2/5 ──────────────────────────────────────────

Skill: skill-creator
Score: Medium
Tokens: 4546
Description: 313 chars
Triggers: 5
Anti-triggers: 0

Issues:
  ⚠️ SKILL.md is 4546 tokens (soft limit 500)

📝 Suggested improvement (anti-triggers):
────────────────────────────────────────
DO NOT USE FOR: general coding questions unrelated to skill-creator, creating new projects from scratch.
────────────────────────────────────────
Apply this improvement? [y/N]y

  Verified: score is now Medium-High

### Flags

| Flag | Default | Description |
|------|---------|-------------|
| `--target` | `medium-high` | Target adherence level |
| `--max-iterations` | `5` | Max improvement iterations |
| `--auto` | `false` | Apply improvements without prompting |

### Implementation

New package `cmd/waza/dev/` with the following files:

- **score.go** — `HeuristicScorer` implementing a `Scorer` interface.
Pattern-matching heuristics for triggers, anti-triggers, and routing
clarity. Validation for name format, description length, and token
budget.
- **loop.go** — The core `runDevLoop` function. Steps through
description expansion, trigger addition, anti-trigger addition, and
routing clarity. Declining a suggestion skips to the next applicable
step rather than ending the loop.
- **display.go** — Terminal output formatting.
- **prompt.go** — User prompts for confirm (y/N). Uses a shared
`bufio.Scanner` to avoid consuming stdin across multiple reads.
- **root.go** — Cobra command registration.

New package `waza/internal/skill` adds `Skill` and `Frontmatter` types
and related un/marshaling functions.

### Preparatory refactor

`internal/tokens` was extracted from `cmd/waza/tokens/internal/tokens`
so the token estimation logic can be shared between the `tokens`
subcommand and the new `dev` package.

E2 sensei engine (#32, #33) shipped but SKILL.md still listed `waza dev`
as "coming soon". Updated documentation to reflect implemented features.

## Changes

**Help text block**
- Added DEV FLAGS section: `--target`, `--max-iterations`, `--auto`
- Updated command summary to include `[skill-path]` argument

**waza dev command section**
- Usage examples for scoring workflows
- Compliance levels: Low → Medium → Medium-High → High with progression
criteria
- Scoring checks: description length (150+ chars, 1024 max), trigger
phrases, anti-trigger phrases, routing clarity markers, token budget
(500 soft / 5000 hard)

**Future features section**
- Marked trigger accuracy tests (#36), `--skip-integration` (#37),
`--fast` (#38), improvement suggestions engine (#34) as "Coming Soon"

```bash
# Score and improve to high compliance
waza dev skills/my-skill --target high

# Auto-apply without prompts
waza dev skills/my-skill --auto --max-iterations 3
```

Current state: waza skill at High compliance (638 chars, 13 triggers, 3
anti-triggers), 2097 tokens.

> ## What's ready to document (blockers spboyer/waza#32 and
spboyer/waza#33 are closed)
> 
> 1. **`waza dev` command usage** — The sensei dev loop is implemented.
Document the command, its flags (`--verbose`, `--target-score`,
`--max-iterations`), and a usage example in the SKILL.md.

scoring system from spboyer/waza#33 is merged).

> - Improvement suggestions engine (#34 — still open)
> 
> ## Files to update
> - `skills/waza/SKILL.md` — the main SKILL.md for the waza skill
> 
> Read the existing SKILL.md first, then update the sections that
reference `waza dev` as 'coming soon' with actual documentation. Keep
the token count reasonable (under 500 tokens for the SKILL.md
