docs(#3389): add product naming guidance to AGENTS.md

[fullsend-ai-coder]

Add "Product name" bullet to the Key Conventions section of AGENTS.md, establishing "Conforma CLI" as the canonical project name and explicitly deprecating the former "ec-cli" name. This prevents code agents from using stale project names found in issue descriptions when generating user-facing strings, error messages, or documentation.

Summary

This PR adds a "Product name" bullet to the Key Conventions section of AGENTS.md, establishing "Conforma CLI" as the canonical project name (binary: ec) and explicitly deprecating the former "ec-cli" name. The change traces directly to issue #3389, a retrospective action item from PR #3381 where the code agent used the stale "ec-cli" name in error messages.

Dimensions reviewed

Dimension	Result
Correctness	✅ No findings. Verified claims against source: binary name ec confirmed in cmd/root/root_cmd.go:68 (Use: "ec"), project name "Conforma CLI" confirmed at line 69 (Short: "Conforma CLI"). Internally consistent with existing AGENTS.md references to ec and ec-work-*.
Security	✅ No findings. Clean ASCII text, no secrets, no injection patterns, no Unicode steganography, no permission changes.
Intent & coherence	✅ No findings. PR scope exactly matches issue #3389's proposed wording and location. No scope creep. Adding to Key Conventions is architecturally appropriate.
Style & conventions	✅ No findings. New bullet follows the established **Bold key:** description pattern with backtick code references, consistent with surrounding bullets.
Documentation currency	✅ No findings. Neither AGENTS.md nor CLAUDE.md contains the deprecated "ec-cli" name.
Cross-repo contracts	⏭ Skipped — no exported interfaces or API surfaces modified.

Verdict

Clean, well-scoped documentation change. No findings across any review dimension. The guidance is technically accurate and appropriately placed in Key Conventions where code agents demonstrably read it.
