detector.findScript matches on substrings of script values (false positives)

[rafaelvieiras]

Problem

findScript('lint') / findScript('coverage') match the keyword against both the script key and its value. A script like "ci": "... eslint ..." can be wrongly elected as lintScript and later invoked as npm run ci -- --format json .... Same fragility for testCoverageScript.

Location

src/installer/detector.mjs:107-114

Suggested fix

Prefer exact/known key matches (lint, lint:js, test:coverage, test:cov, coverage) over substring-in-value matching; only fall back to value matching for unambiguous commands.

Acceptance

• A ci/build script that merely mentions eslint/coverage in its value is not selected.
• Tests covering the disambiguation.
