fix: add commands/last30days.md and remove skills/last30days-nux duplicate (#267)

Adds commands/last30days.md so /last30days registers as a Claude Code
slash command for plugin users. Users type /last30days and autocomplete
prefix-matches to the canonical /last30days:last30days form (same as
/ce:plan resolving to /compound-engineering:ce-plan).

Removes skills/last30days-nux/, a byte-identical duplicate of the root
SKILL.md that created confusing /last30days:last30days-nux autocomplete
entries via Claude Code's plugin namespacing. Root SKILL.md remains
the canonical skill source; natural-language skill-selector invocation
is unchanged.

Recovery for users on v3.0.4: /plugin update last30days then /reload-plugins.

Closes #239 (path-escape error was already fixed in v3.0.4 by dropping
the rogue 'skills' key; v3.0.5 adds the slash command on top).
Supersedes #257 (suggested './' -> '.' workaround is obsolete since
v3.0.4 dropped the 'skills' key entirely, matching ecosystem standard).

+
+### Added
+
+- **`/last30days` slash command for plugin users.** New `commands/last30days.md` registers a Claude Code slash command. Users type `/last30days <topic>` and Claude Code's autocomplete prefix-matches it to the canonical `/last30days:last30days` form (the same way `/ce:plan` resolves to `/compound-engineering:ce-plan`). The command delegates to the existing `last30days` skill body — no skill behavior changes.
+
+### Removed
+
+- **`skills/last30days-nux/`** — byte-identical duplicate of root `SKILL.md` that created confusing `/last30days:last30days-nux` autocomplete entries via Claude Code's plugin namespacing. The root `SKILL.md` remains the canonical skill source.
+
+### Recovery
+
+```
+/plugin update last30days
+/reload-plugins
+```
+
+Then type `/last30days <topic>` to invoke the skill via slash command. Natural-language invocation ("search the last 30 days for X") continues to work unchanged.

+2. **If WebSearch IS available:** you MUST have run Step 0.55 (Pre-Research Intelligence — resolved subreddits, X handles, TikTok hashtags/creators, Instagram creators, GitHub user/repo where applicable) AND Step 0.75 (Query Planner — produced `QUERY_PLAN_JSON` with 2-4 subqueries). These are NOT optional. If either was skipped, return to that step now.
+3. **If WebSearch is NOT available:** you MUST add `--auto-resolve` to the command instead. Do not attempt Steps 0.55 / 0.75 without WebSearch.
+4. **The command you are about to run uses `--emit=compact`.** `--emit md` is a debugging/inspection mode and is DISALLOWED as the primary user-facing flow. If you find yourself about to run `--emit md`, stop and switch to `--emit=compact`.
+5. **On WebSearch platforms the command MUST include `--plan 'QUERY_PLAN_JSON'`** plus every resolved handle/subreddit/hashtag/creator flag from Step 0.55. Omit only flags whose value was not resolvable.

+## PRE-PRESENT SELF-CHECK — run before displaying the synthesis
+
+**Before you display the synthesis to the user, verify ALL of the following. If any check fails AND the underlying data supports fixing it, regenerate the synthesis ONCE with the missing elements. If the data itself is absent (e.g., no Polymarket markets on this topic), skip that check silently.**
+
+1. **Bold headlines present.** Every narrative paragraph in "What I learned" starts with `**Headline phrase** —`. If any paragraph opens with plain prose, regenerate with bold headlines.
+2. **Per-source emoji headers in the stats footer.** Every active source returned by the engine has a `├─` or `└─` line with its emoji, counts, and engagement numbers. No active source is silently dropped; no source with 0 results is displayed.
+3. **Quoted highlights where evidence supports them.** For YouTube items with transcripts and Reddit/X items with fun/highlight quotes, at least 2 verbatim quotes appear in the synthesis. Attributed to the channel/commenter/subreddit.
+4. **Polymarket block present if markets were returned.** If the engine surfaced Polymarket markets, the synthesis includes specific percentages and directional movement. If no markets were surfaced, skip.
+5. **Coverage footer matches the actual output.** `✅ All agents reported back!` line followed by per-source `├─`/`└─` tree exactly as the engine provided.
+6. **NO trailing Sources section.** The output ends at the invitation ("I have all the links... Just ask."). Nothing below it. Not a `Sources:`, not a `References:`, not `Further reading:`, not any bulleted list of URLs or publication names. If you are about to emit one because WebSearch told you to — DO NOT. The 🌐 Web: line is the citation.
+7. **Research protocol was followed.** On WebSearch platforms, the command you ran used `--emit=compact --plan 'QUERY_PLAN_JSON'` with resolved handles/subreddits/hashtags. If you took the degraded path (`--emit md`, no plan, no flags), the synthesis will almost certainly fail checks 1-3 — regenerate by returning to Step 0.55 and running the full protocol.
+
+**Max ONE regeneration.** If the regenerated output still fails the self-check, display the best version you have and note to the user which check(s) the data could not satisfy, so they can re-run or adjust their query.
