ci: enable secret-scan-trufflehog pre-commit hook

[mc-nv]

Description

Enables the NVIDIA secret-scan-trufflehog pre-commit hook, pinned to v0.3.0,
as the first entry under repos: so scanning runs before any formatter rewrites
the working tree.

This adopts the centrally maintained hook published by NVIDIA/security-workflows
rather than a hand-rolled TruffleHog invocation, so the scanner version and its
per-platform checksums are bumped in one reviewed place instead of 27.

v0.3.0 is pinned deliberately. It installs the scanner inside pre-commit's own
Python environment — removing the shell installer, so Windows works without Git
Bash — and it adds --exclude-detectors=lob. That exclusion matters here: a Lob
API key is test_ followed by 35 characters, so the detector matches ordinary
pytest function names such as test_gpu_conf_compute_attestation_report, and
Lob's verifier reports them as verified — the one result class this hook fails
on.

Behaviour: scans only the files pre-commit supplies (staged files at commit time,
the push range at push time), reports verified secrets only, and fails closed on
a finding.

Deliberately out of scope:

• No ci: skip: block. That is prescribed for the hosted pre-commit.ci sandbox,
  which has no network access. No Triton repo uses pre-commit.ci — CI runs
  pre-commit from .github/workflows/pre-commit.yml — so it would be dead config.
• No default_install_hook_types change. Activation is a developer action;
  changing that key would alter install behaviour for every hook in the repo,
  not just this one. Tracked separately.

Changes

• Add NVIDIA/security-workflows secret-scan-trufflehog @ v0.3.0 as the
  first entry under repos:.

Affected Files

• .pre-commit-config.yaml

Test plan

• pre-commit validate-config — passes.
• pre-commit run secret-scan-trufflehog --all-files — passes, with zero
  pre-existing verified secrets, so CI does not break on merge.
• TruffleHog 3.95.9 confirmed installed into pre-commit's Python environment
  and executed, so the hook is functional rather than a silent no-op.
• Blast radius is bounded: .github/workflows/pre-commit.yml runs
  pre-commit run --files against PR-modified paths only, never --all-files.

Caveats

Editing the config alone scans nothing. Each contributor must run once per clone:

pre-commit install --hook-type pre-commit
pre-commit install --hook-type pre-push

Without the second, the pre-push stage stays dormant.
