docs: correct the installer module list

[smini-digital]

What & Why

CLAUDE.md documents lib/installers/ for agents reading the repo, and its module list had drifted: it named grafanactl.js and logcli.js, both removed when gcx replaced them, and omitted four modules that do exist. An agent trusting it would look for files that are not there and miss gcx.js entirely — the one that matters most, since it is what the Grafana tooling is now.

Key Changes

CLAUDE.md — the "Current tools" line now matches lib/installers/ exactly:

• removed grafanactl.js, logcli.js (no longer exist)
• added gcx.js, hcloud.js, ovhcloud.js, playwright.js

Verification

Checked programmatically rather than by eye — the listed set and the on-disk set are compared both ways against origin/main:

listed but missing from disk: none
on disk but not listed     : none
counts: listed 11 | actual 11

npm run lint → exit 0. npm run check-format → exit 0 ("All matched files use Prettier code style!").

The two remaining grafanactl mentions in the repo are deliberate and untouched — README.md and lib/llm/index.js both say gcx replaces the old CLIs, which is exactly what a reader needs to know.

Deployment Notes

Doc-only, and internal to this repo — CLAUDE.md is not part of the published doc set, so nothing reaches consumers' ~/.claude/docs/.

Code Review

This pull request updates the documentation in CLAUDE.md to reflect the current list of tools, removing grafanactl.js and logcli.js while adding gcx.js, hcloud.js, ovhcloud.js, and playwright.js. There are no review comments, and I have no feedback to provide.
