Fix lovable plugin source path to use explicit relative path

[justhamade]

Summary
Updates the source path for the lovable plugin in .claude-plugin/marketplace.json from "plugins/lovable/" to "./plugins/lovable/" to use an explicit relative path reference.
What Changed
File: .claude-plugin/marketplace.json
The source field for the lovable plugin entry was updated:

Before: "source": "plugins/lovable/"
After: "source": "./plugins/lovable/"

Why
The addition of ./ makes the path explicitly relative to the current directory, rather than relying on implicit resolution. This is a more conventional and reliable way to reference relative paths, as some path resolution logic may interpret a bare path like plugins/lovable/ differently depending on the working directory or runtime context. Using ./ removes this ambiguity and ensures the plugin is always resolved relative to the location of the config file.

     ~/.claude/plugins/marketplaces/10K-Digital-lovable-claude-code/.claude-plugin/marketplace.json plugins.0.source: Invalid input

Impact

No functional changes to the plugin itself
No changes to plugin behavior, version, or metadata
Minimal risk — this is a config-only, one-line change
