Walkthrough

This update standardizes logging key names from "err" to "error" across several components and adds detailed comments to struct fields in multiple files for improved code documentation. No logic, control flow, or public API changes are introduced; all modifications focus on code clarity and log consistency.

Changes

File(s)	Change Summary
bidengine/config.go	Added a descriptive comment above the Config struct definition.
bidengine/order.go	Added detailed comments to struct fields and channels; changed log key "err" to "error" in logs.
bidengine/service.go	Added detailed comments to struct fields; updated log key "err" to "error" in three locations.
cluster/inventory.go	Renamed log key "err" to "error" in three places; removed a trailing blank line.

Poem

In fields of code where logs once stirred,
"Err" became "error"—a much clearer word.
Comments now bloom on every line,
Making intent and structure align.
The rabbit hops with pride today,
For clarity has come to stay!
🐇✨

@cloud-j-luna - struct field comments and standardization on "error" make sense and LGTM.

@troian - as it pertains to comment standardization - again all looks good from my perspective. Any concerns on commenting style/content form your perspective?
