`hermes_cli/doctor.py` had two recurring patterns:

1. **15 section headers** of the form `print() ; print(color("◆ Name", Colors.CYAN, Colors.BOLD))`
   bracketed by 3-line `# =====` / `# Check: X` / `# =====` comment banners.

2. **Paired `check_fail(...) ; issues.append(...)`** for every diagnostic that emits both a
   user-visible failure and an auto-fix instruction.

Add two helpers and collapse the patterns:

  def _section(title):
      print()
      print(color(f"◆ {title}", Colors.CYAN, Colors.BOLD))

  def _fail_and_issue(text, detail, fix, issues):
      check_fail(text, detail)
      issues.append(fix)

Replacements:
- 15 `# =====/# X/# =====` banner triples + section header pairs compressed to `_section(...)`
- All 18 `check_fail + issues.append` pairs collapsed to `_fail_and_issue(...)` (single-line
  where the call fits under 120 chars, multi-line where it doesn't)
- Net -5 LOC (`+128 / -133`)

The LOC delta is modest after wrapping long calls onto multi-line form for readability — the
real win is uniform call shape and removal of two parallel-pattern footguns. There is now
exactly one way to emit a diagnostic that pairs a user-visible failure with a fix instruction.

Behavior is byte-identical. `_section` produces the same blank line + bold-cyan output the
inline two prints did, and `_fail_and_issue` does the same `check_fail + issues.append`
sequence in the same order. Verified empirically by diffing live `run_doctor()` stdout from
this branch against `origin/main` — `diff -q` reports zero differences.

Test plan:
- All 69 tests across test_doctor.py, test_doctor_command_install.py, and
  test_doctor_dedicated_provider_skip.py pass
- `ruff check hermes_cli/doctor.py` clean
- Live `run_doctor()` output byte-identical to origin/main

discipline).
