refactor: simplify native module loading and remove unused scripts

- Replace custom install script with standard node-gyp-build usage
- Remove redundant fallback logic in src/syslog.ts
- Delete unused test scripts (test-basic.js, test-direct.js, test-simple.js)
- Remove container-test.js wrapper script
- Trust node-gyp-build to handle module resolution automatically
- Align with Node.js native addon best practices

 - Keep changes tightly scoped to the requested outcome.
 - Refer to `openspec/AGENTS.md` (located inside the `openspec/` directory—run `ls openspec` or `openspec update` if you don't see it) if you need additional OpenSpec conventions or clarifications.
 - Identify any vague or ambiguous details and ask the necessary follow-up questions before editing files.
+- Do not write any code during the proposal stage. Only create design documents (proposal.md, tasks.md, design.md, and spec deltas). Implementation happens in the apply stage after approval.
 
 **Steps**
 1. Review `openspec/project.md`, run `openspec list` and `openspec list --specs`, and inspect related code or docs (e.g., via `rg`/`ls`) to ground the proposal in current behaviour; note any gaps that require clarification.
