## Summary
Exposes the existing variables API through a new `fabro variable` CLI
namespace (`list`, `get`, `set`, `rm`), following the same patterns as
`fabro secret`. Variables are intentionally readable — `list` and `get`
show stored values — while `fabro secret` remains write-only. This PR
also ships a significant set of accompanying changes: a refactored
sandbox lifecycle model in the web UI, removal of the
`fabro-devcontainer` crate, and a new `RunSandbox` OpenAPI schema that
models the full planned → initializing → ready/failed lifecycle.
## What Changed
### CLI (`fabro variable`)
- New `fabro variable` namespace with `list` (aliased `ls`), `get`,
`set`, and `rm` subcommands, dispatched through the same
`ServerTargetArgs` pattern as `fabro secret`.
- `fabro-client` gains five new wrapper methods (`list_variables`,
`get_variable`, `create_variable`, `update_variable`, `delete_variable`)
over the generated OpenAPI client.
- `set` is an upsert; `--value-stdin` accepts empty input after
newline-trimming (unlike the secrets equivalent).
- CLI reference docs (`docs/public/reference/cli.mdx`) regenerated;
`docs/public/workflows/variables.mdx` gains a short section explaining
`{{ vars.NAME }}` interpolation and the variables-vs-secrets security
boundary.
### Sandbox lifecycle model (web)
- New `RunSandbox` OpenAPI shape splits the old flat object into `kind`
(planned/initializing/ready/failed) + `plan` + optional `instance` +
optional `failure`.
- `apps/fabro-web/app/lib/run-sandbox-lifecycle.ts` centralises
lifecycle helpers (`sandboxLifecycleKind`, `sandboxInstance`,
`sandboxRuntime`, `sandboxIsReady`, `sandboxTabVisible`,
`SANDBOX_LIFECYCLE_DISPLAY`).
- Run summary panel and sandbox route now show lifecycle state
(Initializing / Failed with causes / Not created) before or instead of
the fully-loaded `SandboxDetails`.
- The sandbox details query is skipped entirely until `sandboxIsReady`
returns true, preventing unnecessary 404 fetches for planned/failed
sandboxes.
- `runHasSandbox` in `tabs-shell.tsx` delegates to `sandboxTabVisible`,
hiding the Sandbox tab for `planned` state and showing it for
`initializing`/`ready`/`failed`.
- Legacy flat sandbox shape (no `kind`) is handled via
backwards-compatible shims in the new helpers.
### `fabro-devcontainer` removal
- The `fabro-devcontainer` crate has been removed from `Cargo.lock` and
all dependent crates.
- References to devcontainer in internal plans, docs, changelog entries,
and event schemas have been cleaned up or reworded to reflect that the
feature is no longer present.
### Plan summary
- **Unit 1:** `fabro-client` variable wrappers
- **Unit 2:** CLI args, dispatch, and `commands/variable/mod.rs`
- **Unit 3:** `list`, `get`, `set`, `rm` behavior modules
- **Unit 4:** Test harness helpers and integration tests
- **Unit 5:** Regenerated CLI docs + `variables.mdx` update
