What ❔

• Run typos across the full repository and fix historical typos in source, tests, and docs.
• Update _typos.toml to reduce false positives:
  • exclude binary/artifact files,
  • allowlist intentional DSL words (INOT, inot),
  • allowlist asm attribution/acronym words (Wich, TRE) only for asm files.
• Rename typoed public constant EXNTENDED_CONFIGURED_IV -> EXTENDED_CONFIGURED_IV and update in-repo usages.

Why ❔

• Typos CI currently checks changed files only, so historical typos remained in the repository.
• This change cleans the backlog and makes full-repo typos checks reliable while keeping intentional words and generated/asm content noise-free.

Is this a breaking change?

• Yes
• No
