v3.0.5

## What's new

Ships \`/last30days\` as a real Claude Code slash command for plugin users. Type \`/last30days <topic>\` and Claude Code's autocomplete prefix-matches it to the canonical \`/last30days:last30days\` form (same way every other plugin command in the ecosystem works).

## Recovery

\`\`\`
/plugin update last30days
/reload-plugins
\`\`\`

If you were on v3.0.1 - v3.0.3 and saw the \`Path escapes plugin directory: ./ (skills)\` error, that was fixed in v3.0.4. v3.0.5 adds the slash command on top.

## Changes

- Added \`commands/last30days.md\` for slash-command registration
- Removed \`skills/last30days-nux/\` (byte-identical duplicate of root \`SKILL.md\`) that was creating confusing \`/last30days:last30days-nux\` autocomplete entries

## Closes

- #239 (path-escape error)
- Supersedes #257 (workaround obsolete after v3.0.4)
