Proposed Changes

Integrate the crate-ci/typos spell checker into the CI pipeline as a standalone workflow, addressing the revert of the original implementation (#6533) which needed configuration tweaks.

What this PR does:

1. Adds .github/workflows/typos.yml — standalone workflow running crate-ci/typos@v1.43.5 on push/PR to dev
2. Adds _typos.toml configuration — comprehensive config to handle false positives:
   • Excludes non-English READMEs, test fixtures, WAF regexes, embedded certificates, and encoded payloads
   • Preserves exported identifiers (ExludedDastTmplStats, PostReuestsHandlerRequest) to avoid breaking API changes
   • Handles CLI flag abbreviations (-ot, -ue, -hae, -ine, -ines) and external dependency types (goflags.AllowdTypes)
3. Fixes actual typos found by the tool:
   • seperate → separate in lib/tests/sdk_test.go (3 occurrences)
   • fiter → filter in lib/config.go
   • thant → that in pkg/tmplexec/flow/flow_executor_test.go
   • formated → formatted in cmd/tmc/main.go (local variables + log message)
   • worflow_loader.go → workflow_loader.go (filename rename)

Design decisions:

• Standalone workflow instead of embedding in tests.yaml — avoids blocking the test pipeline on spell checking, and was the cause of the original revert
• Conservative approach to exported identifiers — misspelled exported names (ExludedDastTmplStats, PostReuestsHandlerRequest) are added to the ignore list rather than renamed, to avoid breaking API compatibility. These could be addressed in a separate refactoring PR.

Proof

Before (typos found):

$ typos 2>&1 | wc -l
924

After (with config + fixes):

$ typos
(no output — clean pass ✅)

Checklist

• Pull request is created against the dev branch
• All checks passed (typos check passes cleanly)
• Tests verified — no functional code changes, only comment/variable name fixes and filename rename
• Documentation added (_typos.toml config is self-documenting with comments)
