fix: 6 bugs in model metadata, reasoning detection, and delegate tool

Browse Source 
Cherry-picked from PR #2169 by @0xbyt4.

1. _strip_provider_prefix: skip Ollama model:tag names (qwen:0.5b)
2. Fuzzy match: remove reverse direction that made claude-sonnet-4
   resolve to 1M instead of 200K
3. _has_content_after_think_block: reuse _strip_think_blocks() to
   handle all tag variants (thinking, reasoning, REASONING_SCRATCHPAD)
4. models.dev lookup: elif→if so nous provider also queries models.dev
5. Disk cache fallback: use 5-min TTL instead of full hour so network
   is retried soon
6. Delegate build: wrap child construction in try/finally so
   _last_resolved_tool_names is always restored on exception
