YeonGyu-Kim f1e4ad7574 feat: #156 — error classification for text-mode output (Phase 2 of #77) ...

## Problem

#77 Phase 1 added machine-readable error `kind` discriminants to JSON error
payloads. Text-mode (stderr) errors still emit prose-only output with no
structured classification.

Observability tools (log aggregators, CI error parsers) parsing stderr can't
distinguish error classes without regex-scraping the prose.

## Fix

Added `[error-kind: <class>]` prefix line to all text-mode error output.
The prefix appears before the error prose, making it immediately parseable by
line-based log tools without any substring matching.

**Examples:**

## Impact

- Stderr observers (log aggregators, CI systems) can now parse error class
  from the first line without regex or substring scraping
- Same classifier function used for JSON (#77 P1) and text modes
- Text-mode output remains human-readable (error prose unchanged)
- Prefix format follows syslog/structured-logging conventions

## Tests

All 179 rusty-claude-cli tests pass. Verified on 3 different error classes.

Closes ROADMAP #156.
