root 63b2aca8d8 Fix the budget gate and add CI, lint and coverage guards
- check_budget.py escalated a hard index-row violation to 'warn' on both
  branches, so INDEX_ROW_HARD could never fail anything. It fails now, and
  tests/unit/test_budget_measurement.py pins both thresholds.
- The corpus note counted scripts/__pycache__/*.pyc, so the same commit
  reported 27 scripts after the suite had run and 16 on a clean checkout.
- TOKENS_PER_CHAR is re-derived from a measurement (26,795 chars -> 6,065
  tokens = 4.418); the comment's old figure and its arithmetic were both
  wrong for this file.
- check_repo.py's yaml sentinel carries the type ignore, so mypy is clean
  with PyYAML installed as well as without it.
- The CPUID test now skips with the probe's own note on a host without
  CPUID instead of failing, and pytest.ini points at tests/README.md, which
  exists, instead of an EXTENSION file that never did.

Tooling: .flake8 (a measured 120-column limit), .gitattributes, .gitignore
and .github/workflows/ci.yml (the five gates, the suite on 3.11-3.14 and a
lint job), which is what CONTRIBUTING.md already claimed CI runs. The
pull-request template it refers to now exists.

Content: pitfalls P26-P34 -- the analysis-level failures the catalogue was
missing (sampling read as observation, a self-built parser trusted, a
verification that could not have failed, a shell-mangled command line) --
registered in the symptom index and its routing mirror. FINDINGS F11-F15
record the defects above.

Tests: the coverage guard derives its subject from scripts/ rather than a
hand-written list, pe_triage.py and pe_diff.py gain their first tests, and
plan.py / preflight.py are declared uncovered with reasons.

# flake8 configuration for this repository.
#
# Three settings, each with the measurement behind it rather than a preference.
#
# max-line-length = 120
# Measured before this file was added: the longest line across *.py and
# skills/exe-reverse/scripts/*.py is 110 characters (trace_reduce.py:666). 120 leaves room for a
# rule table or a format string written on one line without forcing a split inside a raw regex,
# which either changes the pattern or produces a concatenation harder to read than the long line.
# A line over 120 is a defect to look at, not a style disagreement.
#
# max-complexity is not set, and C901 is excluded below with the measurement: this repository's
# parsers and dispatchers are long flat if/elif chains over finding kinds and PE structures. Setting
# a threshold above the maximum would be a number chosen to pass rather than a standard; splitting
# them into one function per case would move the shape of the format away from the code that reads
# it, and looking like the specification is this repository's argument.
#
# extend-ignore:
# C901 see above -- reported here as a measurement, not enforced
# E203 slice whitespace (`data[start : end]`); flake8 and every autoformatter disagree, and the
# repository has no autoformatter
#
# Run from the repository root:
# flake8 *.py skills/exe-reverse/scripts/*.py
#
# Enforced in CI: the `lint` job in .github/workflows/ci.yml runs this exact command alongside mypy,
# on a bare interpreter, so the configuration is exercised in the poorest environment it must keep
# working in.
