Overview

Sandbox primitive (COMPETITIVE-ANALYSIS): a single, pluggable interface for confined execution, promoted to the core from the insika-code prototype. Two halves:

* FS confinement (`Boundary`) — ALWAYS host-side, always on: every path a
tool resolves is proven inside the root before any IO.
* command exec — via a swappable PROVIDER: `local` (in-process, the default)
or `docker` (isolated container). Providers are chosen by DATA, not code
(config-over-code): the agent profile's `sandbox` block names the provider
and its policy.

Env is the object a tool holds; Sandbox.build(config) assembles one from the declarative config (the same hash shape stored on the profile).

.build(config = {}) ⇒ Object

config keys (all optional, string or symbol):

provider    "local" (default) | "docker"
root        confinement root (default: Dir.pwd)
timeout     per-exec wall-clock seconds (default 120)
max_output  bytes of combined output kept (default 40_000)
+ provider-specific keys (image/network/memory/cpus/... for docker)
