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 workaround is obsolete since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).

+## [3.0.5] - 2026-04-15
+
+### 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.
