Drop "skills": ["./"] to fix v2.1.105 load regression

The harness rejects "./" in the skills array with
  Path escapes plugin directory: ./ (skills)
even though 2.1.94's changelog explicitly sanctioned this pattern.
This prevents the plugin from loading on current releases.

"./" also created a latent duplicate name: it registered the root
SKILL.md as "last30days", while auto-discovery of
skills/last30days-nux/SKILL.md (a symlink to ../../SKILL.md) registered
the same content under the same name. The duplicate only surfaced once
the registration succeeded.

Dropping "./" makes skills/ auto-discovery the single source for the
harness: skills/last30days-nux/ registers as "last30days", and
skills/last30days/ registers as "last30days-v3-spec" via its frontmatter
name. The root SKILL.md continues to serve the other harnesses that
rely on it (.agents/, .hermes-plugin/, .codex-plugin/, gemini-extension).

+### Gemini CLI
+
+Gemini CLI supports installing extensions from GitHub repositories, but as of Gemini CLI v0.9.0 there is an upstream installer bug that can fail with:
+
+`Configuration file not found at /tmp/gemini-extensionXXXXXX/gemini-extension.json`
+
+even when `gemini-extension.json` exists at the repo root.
+
+Upstream bug:
+- https://github.com/google-gemini/gemini-cli/issues/11452
+
+Workarounds:
+1) Clone locally, then install from the local path
+   ```bash
+   git clone https://github.com/mvanhorn/last30days-skill
+   gemini extensions install ./last30days-skill
+   ```
+2) If GitHub install fails, use the OpenClaw or Claude Code install paths above.
+
 ### Manual
 ```bash
 git clone https://github.com/mvanhorn/last30days-skill.git ~/.claude/skills/last30days
