Add --fail-on-error to the host link command - #453

Fixes #269

Summary

• add --fail-on-error to the host link command
• preserve the current default behavior, which warns and skips dependencies that cannot be resolved
• route the opt-in mode through dependency discovery so Node's original resolution error is printed and the CLI exits unsuccessfully
• document the option and add a minor changeset

The strict resolver is internal and separate from the existing tolerant wrapper. That keeps the default API/behavior intact and lets the diagnostic logging work in #451 land independently; I will rebase this PR if that resolver change merges first.

Tests

The CLI integration fixture declares broken-package with an exports target pointing to a missing file:

• default link --android: exit 0 and emit the existing warning
• link --android --fail-on-error: exit 1 and include broken-package plus missing.js, not an unknown-option error

TDD evidence: the strict-mode test initially failed because the CLI reported unknown option '--fail-on-error'; it passes after the implementation.

Validation

• pnpm install --frozen-lockfile — Node 24.16.0 / pnpm 10.33.0
• pnpm run build
• focused CLI test — 4/4 passed
• pnpm test — 109/109 passed across host, cmake-rn, and gyp-to-cmake
• pnpm lint
• pnpm prettier:check
• pnpm depcheck
• runtime react-native-node-api help link — option present
• git diff --check
