fix: show local agent config names

[mturac]

Summary

• initialize local agent profile titles from the YAML name: field when .continue/agents/*.yaml files are discovered
• keep the filename fallback for unnamed or invalid YAML configs so the selector remains usable
• cover both display-name and fallback behavior in LocalProfileLoader tests

Fixes #12345

Tests

• npm run vitest --prefix core -- config/profile/LocalProfileLoader.vitest.ts
• npm run tsc:check --prefix core
• npm run lint -- --quiet config/profile/LocalProfileLoader.ts config/profile/LocalProfileLoader.vitest.ts from core/
• npx prettier --check core/config/profile/LocalProfileLoader.ts core/config/profile/LocalProfileLoader.vitest.ts

Summary by cubic

Show the YAML name as the display title for local agent configs in the selector, with sensible fallbacks to keep it usable. Fixes #12345.

• Bug Fixes
  • Parse name from the override YAML and set LocalProfileLoader title.
  • Fallback to the filename when name is missing or YAML is invalid; use "Local Config" when no path.
  • Added tests covering named and fallback cases.
