fix(terminal): support claude-sonnet-4-5 model name formatting

ryoppippi · ryoppippi · commit 0822e4fe82f1 · 2025-10-01T12:00:22.000+01:00
Updated the model name regex pattern to properly handle version numbers
with hyphens (e.g., claude-sonnet-4-5-20250929). Previously, only single
digit versions were supported (e.g., claude-sonnet-4-20250514).

Changes:
- Modified regex from /claude-(\w+)-(\d+)-\d+/ to /claude-(\w+)-([\d-]+)-(\d{8})/
- Added [\d-]+ pattern to match multi-part version numbers like "4-5"
- Updated JSDoc examples to include claude-sonnet-4-5-20250929 format
- Added test cases for Claude 4.5 and mixed version formats

Fixes the issue where claude-sonnet-4-5-20250929 was being displayed as
"sonnet-4" instead of "sonnet-4-5" in usage reports.
