Docs: scrub public workspace references

[postmunnet]

Summary

• Replace public docs references to internal workspace names with generic placeholders.
• Replace the actual-password example placeholder with replace-me.
• Keep export scrub rules generic instead of naming a local workspace folder.

Leak Scan Context

GitHub main scan found no real private key or live API token. These changes address public hygiene markers only:

• yai_project → workspace-root / <workspace-root>
• TRINITY_ULTIMAT → TRINITY_LEGACY
• actual-password → replace-me

Verification

rg -n "actual-password|TRINITY_ULTIMAT|yai_project|stick-vape|rtbpf|/Users/yai" .
python3 -m pytest .ai/cli/tests -q

Result:

rg: no matches
1860 passed, 8 skipped in 13.80s
