fix(guide): skip pinned tools from upgrade prompts

Fixed bug where pinned tools were still being prompted for upgrades
even though they had pinned_version set in their catalog entries.

Previous logic: Only skip if pinned_version >= latest_version
Problem: This meant pinned tools with newer versions available
         would still be prompted for upgrade

New logic: Skip any tool with pinned_version set (except "never")
Behavior: Pinned tools are completely excluded from upgrade prompts,
          which is the expected behavior of version pinning

Examples:
- ctags pinned to 5.9.0 (latest 6.2.1) → now skipped
- node pinned to 25.0.0 (latest 25.1.0) → now skipped
