fix(claude): scan skills/ directory to expose all skills

[mnovelo]

What

Switch .claude-plugin/plugin.json's skills field from an explicit 5-path array to the directory string "./skills/", matching .codex-plugin/plugin.json.

Why

skills/ contains six skills, but the Claude manifest enumerated only five — omitting firecrawl-research-index. Because this marketplace entry's source resolves to the marketplace root ("source": "./"), an explicit skills array replaces the default skills/ scan rather than supplementing it, per the plugins reference:

for a marketplace entry whose source resolves to the marketplace root, declaring specific subdirectories replaces the default skills/ scan

So the unlisted skill never loads when the plugin is installed via the marketplace.

The sibling manifests already expose all six: .codex-plugin/plugin.json uses "skills": "./skills/" and .cursor-plugin/plugin.json omits the field (default discovery). Only the Claude manifest drifted — firecrawl-research-index currently ships to Codex and Cursor users but not Claude.

Effect

• All skills under skills/ load via Claude, including firecrawl-research-index.
• Future skills are picked up without a manifest edit (parity with Codex).

Open question for maintainers

README.md and AGENTS.md enumerate only the five firecrawl-build-* skills. If firecrawl-research-index is meant to ship, those docs likely want a matching entry. If it was deliberately scoped out of the Claude plugin specifically, say so and I'll switch this to explicitly appending the single path instead — though it already reaches Codex/Cursor users either way.
