fix(odin): dedupe tool-trace chips — one per tool, warning only if all attempts failed

A failed call followed by a successful retry showed two identical chips
(one orange). Retries are loop mechanics: the trace now carries one entry
per tool with ok = delivered-at-least-once, for live chips and persisted
history alike (also keeps meta.tools under its 30-entry cap).
