fix formatApiHost (#10236)

* Add .codebuddy and .zed to .gitignore and fix formatApiHost

Prevent formatApiHost from processing undefined/empty host values and
ignore editor-specific directories

* Refactor reasoning tag selection logic for providers

Move gpt-oss model handling from aws-bedrock case to openai case and
consolidate tag selection logic into a single if-else chain.

* Extract reasoning tag name into helper function

* fix test

* Replace array indexing with named object properties for reasoning tags

Improves code readability by using descriptive property names instead of
magic array indices when selecting reasoning tag names by model type.

* Move host validation to start of formatApiHost
