Plugin deduplication incorrectly removes plugins with index.js entry points

[guazi04]

Description

Bug Description
When multiple plugins have entry points named index.js or index.ts, only the last one is loaded. Earlier plugins are silently removed.
Root Cause
getPluginName() returns only the filename for file:// URLs. Since most plugins use index.js/index.ts as entry points, they all return "index" and get deduplicated.
Reproduction
Config with two plugins:
"plugin": ["oh-my-opencode", "file:///path/to/my-plugin/src/index.ts"]
Result: oh-my-opencode is removed because both resolve to name "index".
Environment

• OpenCode v1.1.42
• Windows 11

These issues all describe the same root cause: plugin deduplication logic that doesn't properly account for multiple local plugins or plugins with identical entry point filenames.

Feel free to ignore if your specific case differs from these.

This is addressed by #15598 which adds node_modules-aware path parsing to getPluginName(). CI is green.

The root cause is that import.meta.resolve resolves npm plugins to file://…/node_modules/<pkg>/dist/index.js, and then getPluginName() extracts only the filename "index", causing false collisions with any project plugin that also has an index.ts entry point.
