fix(sdk-review): FP-H/I/J — lockfiles, .env templates, LIC baseline auto-detect

Three new FP classes discovered in the post-remediation dry-run (85 real Python
PRs, 10 Java PRs). Empirical validation showed the initial fix wave left
gaps that produced 1000+ noise findings on subsequent PRs.

- FP-H-01: HC-01 no longer scans lockfiles (uv.lock, poetry.lock, Pipfile.lock,
  package-lock.json, yarn.lock, Cargo.lock, Gemfile.lock, *.lock). These are
  generated files full of package registry URLs. Impact: eliminates ~800
  false BLOCKs on PRs that touch uv.lock.

- FP-I-01: HC-01 no longer scans .env / .env.* / .env_* / .env-* files.
  These are convention/template files carrying placeholder URLs like
  'your-api-url-here'. Impact: eliminates ~14 false BLOCKs.

- FP-J-01: check-license-spdx auto-detects whether the repo has consistent
  SPDX adoption. If < 20% of existing files carry SPDX headers, LIC-01/02
  is held (returns PASS with a pass_criteria_met explanation) rather than
  penalizing every new file for a debt the repo itself carries. Impact:
  eliminates 12 false BLOCKs on cloud-sdk-java PR #6 (Number Range module).

Regression tests: +5 bats tests in test_fp_remediation.bats (76 total, all
green in both repos).
