fix(ci): remove orphan <<<<<<< HEAD merge-conflict markers in ci.yml

A prior merge landed with seven unresolved `<<<<<<< HEAD` lines (each
sitting directly after a `steps:` line) and no matching `=======` /
`>>>>>>>` counterparts, so GitHub Actions (and any other YAML parser)
cannot load the workflow. Removing the orphan markers is a safe no-op
for the intended workflow definition.

Verified the file parses as valid YAML after the change and all seven
jobs (frontend-lint, frontend-type-check, frontend-build, frontend-e2e,
orchestrator-build, contracts-compile, contracts-test) are still defined.
