Remove the two utils/ wrapper packages under interactive_shell

## Goal There is no `utils.py` or `helpers.py` file anywhere under `surfaces/` — the house style is role-named modules. Two `utils/` *packages* survive, and neither holds anything general: each is a single-member directory whose name says only "things nobody placed". ## What is there ``` surfaces/interactive_shell/utils/ __init__.py "Shared interactive-shell utilities." <- says nothing telemetry/ config, recorder, sinks, console_capture, investigation_analytics, turn_outcome, ... surfaces/interactive_shell/runtime/utils/ __init__.py "Runtime utility helpers ..." <- says nothing input_policy.py exclusive-stdin / spinner policy ``` Both `utils/` layers hold exactly one member. Deleting them loses nothing and each import site gains a name that states what it imports. ## Target Two independent moves, both in this PR: 1. `interactive_shell/utils/telemetry/` → `interactive_shell/telemetry/`, then delete `interactive_shell/utils/` 2. `interactive_shell/runtime/utils/input_policy.py` → `interactive_shell/runtime/input_policy.py`, then delete `interactive_shell/runtime/utils/` No file contents change beyond the import lines. There are 12 import sites for the first and 2 for the second — plus a comment in `command_registry/cli_parity.py` and a line in `surfaces/interactive_shell/AGENTS.md` that both spell the old path. ## Acceptance - [ ] `find surfaces -type d -name utils` prints nothing - [ ] `grep -rn "utils.telemetry\|runtime.utils" --include='*.py' .` prints nothing, and neither does the same grep over `*.md` - [ ] `git diff -M --stat` shows renames, not rewrites — no function body moved or edited - [ ] The REPL starts and a turn runs: `uv run opensre` → send one message → exit - [ ] Telemetry still records. Prompt logging is on unless `OPENSRE_PROMPT_LOG_DISABLED` is set, so point it somewhere you can watch: ``` OPENSRE_PROMPT_LOG_PATH=/tmp/sf02.jsonl uv run opensre ``` run one turn, then confirm `/tmp/sf02.jsonl` gained a line. An import that silently stops being reached would not fail any test. - [ ] `make lint format typecheck test` ## Out of scope `core/tool_framework/utils` — that is a different package, outside `surfaces/`, and several tools import from it.
