Fix spelling mistakes

[chavic]

While I was scanning the repo, my AI went rogue and started fixing unrelated issues. This PR took a few of those and only contains:

• Fix spelling and typo issues in docs, changelogs, comments, and release checklist text.
• Correct the misspelled test utility helper name.

Figured not to waste the tokens

ACK a1f7b8c

All but one of the changes exclusively update informational code (comments, md files), and the one code change is a public function renaming in the test utils that seems appropriate to me as it fixes a typo. Would like to know what the protocol is for updating a public function name like this though.

[xstoicunicornx]

Is there additional communication/followup that is needed to change a pub fn name?

[chavic]

Nice catch 🤔

Don't necessarily need a follow-up communication... Currently believe this method isn't widely used but double checking this later

[caarloshenriq]

I looked in the codebase and this method is never called anywhere

[benalleng]

Its ok to just make breaing changes in the test-utils for now. This lives at 0.0.1 for a reason still

Mind sharing the prompt / prompts that resulted in this change I think its relevant as related to #1378

@benalleng Sure, so every time I start a new session, I try to feed codebase patterns, so it can search faster later. Still, it seems the past few hours the agent has been trying to do more, so while I had the agent in the background executing on this prompt: your goal is to master the repository and all the concepts and architectural decisions it's based around, I noticed in a different session that 90% of my 5hr limit was used up, turns out the first agent went around fixing things while it was following the code flow. #1666 was one of these changes, too.

What I think happened, twice now in the last 16 hours, since I got a codex update, the agent has been making its own goals in the background. The worst case is that it just runs out of tokens attempting some self-defined goals, but I can see it being more useful... this is probably a glitch in the goal system that keeps self-prompting until goal status is achieved or blocked, for example, if it's pursuing a goal and you tell it to stop without using /goal clear, it enters a self prompt standby loop until you actually clear the goal or say "continue". Non-deterministic at the core, though
