Conversation
Add `lstk snapshot inspect <file>`, an offline size breakdown of a local .snapshot archive — no running emulator, no platform call, no auth. It opens the ZIP and tallies bytes per service, combining each service's control-plane state (api_states/) and data-asset payloads (assets/) and aggregating across accounts and regions. Output is one row per service, sorted largest-first, with percentages and a grand total; --json emits the same data for scripts and agents. Cloud (pod:) refs are rejected and pointed at `snapshot show`. Complements `snapshot show`, which reports cloud metadata and resource counts.

We are adding json output format for the first time here. What about removing it from here, but do an overall implementation later over all commands that return structured data? My biggest worry is that this becomes the contract we have to stick to as soon as we release it and we should be deliberate about how we format this json (case, structure etc). |

Good observation! 😁 Absolutely, already tracked in PRO-307 (draft branch). I will remove from this PR. |

What
Adds
lstk snapshot inspect <file>— an offline, per-service size breakdown of a local.snapshotarchive.No running emulator, no platform call, no auth.
Why
snapshot showis cloud-only and reports resource counts plus one aggregate size — it can't answer "what's eating the space in my local snapshot?".inspectreads the archive directly and attributes bytes per service, combining each service's control-plane state (api_states/) and data payloads (assets/), aggregated across accounts and regions.Details
.snapshotZIP with stdlibarchive/zipand tallies sizes per entry — no emulator, platform, or auth.--jsonemits the same data (raw bytes) for scripts and agents.pod:) refs are rejected and pointed atsnapshot show.SnapshotInspectedEventwith plain + TUI rendering parity. Unit + integration tests; no Docker required.Fix PRO-322.
