refactor(skill): replace SKILL_ROOT resolver with SKILL_DIR substitution

The Step 1 and comparison-mode resolver loops walked a hardcoded list
of install paths trying to find scripts/last30days.py. Two problems:

1. The list was never exhaustive — it covered ~/.codex/skills, but not
   ~/.claude/skills, ~/.cursor/skills, ~/.gemini/skills, ~/.copilot/skills,
   ~/.hermes/skills/research, etc. PR #406 was about to fix that by
   enumerating more paths, but enumeration is the wrong shape.
2. The resolver could pick a different install than the SKILL.md the
   model loaded from. Spec-vs-engine divergence is subtle and confusing
   when it triggers.

The model already knows the SKILL.md path it loaded (from its Read tool
result). Templating that into the bash block is strictly better than
guessing across an enumerated list:

- Works for every harness without enumeration (Hermes, Cursor, anything
  new) because we just use wherever the harness loaded SKILL.md from
- Aligns spec with engine — the engine runs from the same install the
  spec was read from
- Deletes ~80 lines of bash across Step 1 + comparison-mode + the
  prose preamble describing the resolver

Mechanics:

- SKILL_DIR placeholder in both bash blocks — model substitutes the
  absolute path of the directory containing the SKILL.md it just Read
- One-line validation `[ ! -f "$SKILL_DIR/scripts/last30days.py" ]`
  catches bad templating with a clear error
- All references to $SKILL_ROOT replaced with $SKILL_DIR (badge
  VERSION lookup, prose description in the LAW-7 preamble area)
- STEP 0 unchanged — different concern (marketplaces stale-clone hop)

Version 3.2.3 -> 3.2.4 (behavior change: install paths the resolver
list never enumerated now work; install paths it did enumerate work
the same way they used to but via the SKILL_DIR template).

**How v3.0.7 fixes it:** three structural anchors.
1. **The MANDATORY first-line badge** (`🌐 last30days v{VERSION} · synced {YYYY-MM-DD}`) at the top of every response is the LAW 2 / LAW 4 enforcement anchor. See "BADGE (MANDATORY, FIRST LINE OF OUTPUT)" in the synthesis section.
2. **The SKILL_ROOT resolver** in the engine Bash calls walks a precedence list of known install locations and picks the highest-versioned freshest copy, never `~/.openclaw/` or other stale copies.
2. **The SKILL_DIR substitution** in the engine Bash calls uses the directory of the SKILL.md the model just Read — no resolver list, no precedence walk. Whichever install the harness loaded SKILL.md from is the install whose engine runs. Aligns spec-with-code and works for any harness without enumerating its install path.
3. **This preface** tells you plainly: do NOT improvise. Follow SKILL.md top to bottom.
If you catch yourself about to write a `##` section header in a GENERAL-query body, a custom title line, a `Sources:` bullet list, a `for dir in ...` path-discovery loop, or a bare `python3 scripts/last30days.py "{TOPIC}"` engine call with no pre-flight flags — stop. Those are the exact failure modes the LAWs and this contract exist to prevent. The 10/10 beta validation from 2026-04-18 and the 0/8 public v3.0.6 regression from the same day had THE SAME MODEL and SIMILAR SKILL.md CONTENT; the delta is the three anchors this release restores. Read SKILL.md top to bottom before emitting your first response.

**Why the badge is MANDATORY:** it is the structural anchor for the canonical output shape. Without it the model drifts into blog-post narrative format with `##` section headers and invented titles, violating LAW 2 and LAW 4. The 2026-04-18 public v3.0.6 0/8 regression produced outputs with section headers like "The headline", "Why he is everywhere", "1. gstack dominates", "The 'Homecoming' peak". Direct cause: this anchor was absent. Do NOT skip the badge. Do NOT describe it. Do NOT paraphrase it. Emit it verbatim as line 1.
