fix: patch generated web diagnostics

[mattbaconz]

Summary

• fix Problems focus to show the changed excerpt for the verifier diagnostic file
• normalize diagnostic paths like src/App.tsx:1:1 before generated-web retry policy extracts artifacts
• make the local chess rules test seed runner-agnostic so it does not require a Vitest import
• bump CLI/npm package metadata to v0.14.1 and add release notes

Verification

• cargo fmt --all -- --check
• cargo test --locked --workspace
• cargo clippy --locked --workspace --all-targets -- -D warnings
• cargo build --release --locked -p phonton-cli
• target/release/phonton.exe version -> phonton 0.14.1
• target/release/phonton.exe --help
• npm run test:npm-wrapper
• npm pack --dry-run

Keep fast-fail scoped to generated-app subtasks

The new artifact detector treats any diagnostic path ending in .tsx/.jsx as a generated-web artifact, so should_stop_before_generated_app_syntax_repair now fast-fails on first-attempt syntax errors even for non-generated React edits (for example, ordinary repo tasks that fail on src/App.tsx:1:1). That skips the normal repair retry loop and can prematurely fail user tasks that previously self-recovered.
