feat(integrations): add omp support (#3107)

* feat(integrations): add omp support

* Update updated_at timestamp

* refactor(integrations): delegate omp build_exec_args to base, register in issue templates

Inherit MarkdownIntegration.build_exec_args so omp picks up shared CLI
contract changes (requires_cli gating, extra-args ordering, --model
handling) automatically; only specialize the --mode json flag.

Also add Oh My Pi / omp to the issue-template agent lists so
test_issue_template_agent_lists_match_runtime_integrations passes.

* fix(integrations): use --print + positional prompt for omp argv

OMP's CLI parser treats `-p`/`--print` as a boolean (one-shot mode)
and consumes the prompt as a positional message; the previous
inherited `-p <prompt>` shape worked by accident only because `-p`
ignores its next token. Build the argv explicitly with flags first
and the prompt as a trailing positional, matching upstream args.ts.
