[Feature Request] Add native voice input with multilingual support and technical identifier preservation

Bug Description
Claude Code currently has no built-in voice input. Developers who want to dictate tasks — non-English native speakers, solo founders, developers with RSI, people working on the go — are forced to use external tools like Whispering, Wispr Flow, or Superwhisper and paste transcriptions into the terminal or Desktop app.
For Russian (and likely other non-Latin languages) this is especially painful:

Whisper transcribes words well but mangles technical identifiers: variable names, filenames, and paths get transliterated into Cyrillic
Russian smart quotation marks («») and em-dashes (—) break command parsing
Copy-paste workflow = constant context switch, productivity loss

Proposal
Add a native voice input mode to CLI and Desktop:

CLI: claude --voice flag or in-session hotkey
Desktop: dedicated mic button / hotkey
iOS/Android: native microphone recording

Key requirements

Automatic language detection for dictation (en/ru/mixed)
Smart identifier preservation — technical terms, filenames, variables, paths stay in Latin script regardless of dictation language. Example: "save in leads controller dot ts a function create lead" → save in leadsController.ts a function createLead
Built-in vocabulary of stack technologies (React, Postgres, Docker, Next.js…) recognized as identifiers and never transliterated
Punctuation normalization before parsing (smart quotes → straight quotes, em-dash → hyphen)
"Voice → Plan → Approve → Execute" mode: dictation flows into Plan Mode first; code executes only after user confirmation

Use cases

Solo founders dictating tasks from phone in transit, returning to a ready PR
Work in transit / hands-free coding
Non-English native speakers — significantly lowered barrier to entry
Accessibility: developers with RSI or wrist injuries
Rapid prototyping: describe a feature in 30 seconds of voice vs 5 minutes of typing

Reference
Whispering (open-source) with whisper-large-v3-turbo and the "Recommended" preset shows that Russian transcription quality is already production-ready. The task is removing friction between transcription and Claude Code.
Why this matters for Claude Code specifically
AI coding tools are the sweet spot for voice-first workflows: describing intent out loud is often faster than typing. Cursor, Windsurf, and Copilot haven't shipped a native solution. First mover here captures significant competitive advantage among international developers, accessibility users, and mobile-first workflows.
