fix: remove unsupported '--' separator from wasmtime commands

The TinyGo file operations component doesn't accept '--' as an argument
separator. All wasmtime run commands in the performance workflow have been
updated to call the component directly without the separator.

Changes:
- Removed '--' from all wasmtime commands in benchmark steps
- Removed '--' from resource profiling commands
- Removed '--' from performance regression detection commands

This fixes the hyperfine benchmark failures in the Performance Monitoring workflow.

Tested locally:
- Regular component build: ✅
- AOT component build: ✅
- OCI image build: ✅
- Component execution: ✅
