refactor(skill): replace SKILL_ROOT resolver with SKILL_DIR substitution

Browse Source 
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).

### Changed
- Replace the SKILL_ROOT resolver loops in Step 1 and comparison-mode with a single `SKILL_DIR` substitution pattern. The model templates the absolute path of the SKILL.md's own directory (which it always knows from the Read tool result); the bash block just validates that `scripts/last30days.py` lives there. Removes ~80 lines of bash across the two locations. Fixes a real bug: the previous resolver could pick a different install than the SKILL.md the model loaded from (spec-vs-engine divergence) and didn't enumerate harnesses like Hermes at all. The simplification works for any harness without enumeration because it just uses wherever SKILL.md was loaded from. STEP 0's marketplaces-stale-clone hop is unchanged.
- Rename "Digg AI 1000" to just "Digg" in user-facing output (footer line, source label, inline-quote suffix, why_relevant, container attribution). Internal references to the upstream Digg AI 1000 product remain in code comments and docstrings.
- Bump `POSTS_PER_CLUSTER` from 3 to 5 and the render-side display limit from 2 to 3 to match the per-source enrichment caps used by Reddit, HN, YouTube, TikTok, and GitHub. The previous 3/2 caps routinely truncated cluster context (e.g. dropped a Jason Calacanis quote tweet on a `cli-printing-press` run).
- Rewrite SKILL.md path resolution. STEP 0 narrows from a global canonical-path enforcement to a Claude-Code-marketplaces-only stale-clone guard. Step 1 SKILL_ROOT resolver walks a single precedence list (Claude plugin cache, then `~/.codex/skills/`, `~/.agents/skills/`, repo checkout, `./.skills/last30days` for `npx skills add`, CWD, Gemini). Adds SKILL.md frontmatter fallback to `render.py::_skill_version` so the badge no longer prints `v?` on installs that don't include `.claude-plugin/plugin.json`.

**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.
