Warn when existing settings.json is invalid JSON

Problem Statement

When an existing settings.json cannot be parsed, the error is silently swallowed and the file is overwritten. Users get no warning that their settings were discarded.

Findings

• src/targets/gemini.ts lines 37-41: empty catch block

Proposed Solution

Add a console.warn in the catch block to inform the user that their existing settings.json could not be parsed and will be replaced.

Acceptance Criteria

• console.warn emitted when settings.json parse fails
• File is still replaced (behavior unchanged)
• All tests pass
