type error fixes + cleanup

[bmdavis419]

Greptile Summary

This PR adds a new RWX-based CI/CD pipeline (.rwx/ + .captain/), wires up a lint:all script through Turbo, and fixes a TypeScript error in snapshot.ts by replacing import.meta.main with a manual URL comparison. The infrastructure changes are additive and don't touch existing runtime behavior, but there are a few things to address:

• Tests skipped on PRs — .rwx/pr.yml runs lint and type-check but never the test suite. Broken tests will only surface after merging to main.
• Lockfile unenforced in CI — --frozen-lockfile is commented out in .rwx/ci.yml, making dependency installs non-reproducible until the TODO is resolved.
• snapshot.ts deviates from Bun-first style — swapping import.meta.main for a process.argv[1] URL comparison works in practice but goes against AGENTS.md, and is fragile with special-character paths. Fixing the tsconfig to include bun-types is likely the cleaner solution.
• No plan .md files were found in the repository.

Confidence Score: 3/5

• Safe to merge with low risk to existing runtime behavior, but the PR workflow gap means tests aren't gating PRs.
• All existing features are unaffected — the changes are additive (CI config, new Turbo task) or isolated to a sandbox helper. The main concerns are the missing test gate in pr.yml and the disabled lockfile check, both of which are process/CI issues rather than runtime regressions.
• .rwx/pr.yml (missing test step) and .rwx/ci.yml (disabled --frozen-lockfile)

Important Files Changed

Filename	Overview
apps/sandbox/src/snapshot.ts	Replaced Bun-native import.meta.main with a manual process.argv[1] URL comparison; functional in common cases but fragile with special-character paths and deviates from the project's Bun-first style guide.
.rwx/pr.yml	New PR CI workflow — missing a test step, so broken tests won't be caught before merging to main.
.rwx/ci.yml	New main-branch CI workflow; --frozen-lockfile is disabled with a TODO, making dependency installs non-reproducible until resolved.
.rwx/main.yml	New orchestration file that fans out CI runs for x86_64 and arm64 on pushes to main — no issues found.
.captain/config.yml	New Captain test-suite config for retry support — straightforward, no issues.
package.json	Added lint:all script wired to turbo lint — clean, additive change.
turbo.json	Added lint task with dependsOn: ["^lint"] to match the new lint:all script — no issues.

Comment:
**Deviation from Bun-idiomatic approach**

`import.meta.main` is the Bun-native way to check if a module is the entry point (documented in Bun's APIs). The new code uses `process.argv[1]`, which is a Node.js-style API, and AGENTS.md says to prefer Bun APIs over Node equivalents.

If the original code had a TypeScript type error, the simpler fix would be to ensure the package's `tsconfig.json` has `types: ["bun-types"]` (since `@types/bun` is already a root dev dependency). The manual URL comparison is also fragile — `encodeURI` and Bun's internal URL encoding for `import.meta.url` can differ for paths containing characters like spaces or brackets, causing `isMainModule` to be `false` even when run directly.

```suggestion
if (import.meta.main) {
```

Comment:
**Lockfile enforcement disabled**

`--frozen-lockfile` is commented out with a TODO. Without it, `bun install` can silently update packages during CI, making builds non-reproducible and potentially introducing unexpected dependency changes. This should be re-enabled as soon as the packages are updated.

Comment:
**Tests not run on PRs**

The PR workflow ends with the `check` (type-check) step and never calls the `test` task. By contrast, `.rwx/ci.yml` does run tests on the main branch. This means broken tests can be merged through a PR without being caught until after they land on `main`.
