chore(#1175): remove dead tool-name converters + fix unused-arg lint (#1234)

Removes three unreferenced functions from bin/install.js:
- convertCursorToolName (zero callers across src/, bin/, scripts/, tests/)
- convertWindsurfToolName (zero callers across src/, bin/, scripts/, tests/)
- convertAugmentToolName (zero callers across src/, bin/, scripts/, tests/)

Dead code only — behavior-preserving. All three were superseded when
the conversion logic moved to src/runtime-artifact-conversion.cts.
lint and build both clean.
