Strip narrative comments and module/helper docstrings

Five rounds of sweep across the tree. Net ~544 lines removed.

Removed:
- Section-divider banners and one-line section labels (# Display
  utilities, # ----- list_requests -----, # CVSS breakdown, etc.).
- Module-level prose docstrings on internal modules. Kept one-line
  summaries; trimmed multi-paragraph narration about SDK/Strix
  responsibility splits, cache strategies, three-source precedence.
- Internal-helper docstrings that just restate the function name —
  caido_api helpers (caido_url, get_client, view_request, etc.),
  settings-class one-liners (LLMSettings, RuntimeSettings, ...),
  UI helper docstrings.
- Args/Returns blocks on non-LLM-facing internal helpers
  (build_strix_agent, render_system_prompt, create_or_reuse,
  bootstrap_caido) — kept only the genuinely non-obvious params.
- Internal-history phrasing — "Mirrors main-branch shape",
  "pre-SDK harness", "previous lookup matched no attribute".
- Narrative comments inside function bodies that explained what the
  next line does, design rationale obvious from the surrounding code,
  or "we used to..." asides.
- Trailing periods on every error-string literal across the tool tree.
- Duplicated roundtripTime quirk comment (kept the LLM-facing copy in
  tools/proxy/tools.py).

Kept (every one names an upstream bug, vendored-code provenance, or
non-obvious data quirk):
- core/runner.py: SDK replay-with-empty-initial-input + on_agent_end
  lifecycle gap.
- runtime/docker_client.py: VERBATIM COPY block of the upstream
  _create_container body, pinned to SDK v0.14.6.
- runtime/session_manager.py: NO_PROXY for agent-browser CDP loopback.
- tools/proxy/caido_api.py: generated-pydantic Request.raw quirk,
  replay double-history pitfall.
- tools/proxy/tools.py: Caido roundtripTime=0 quirk for proxy
  captures.
