Himanshu Dongre 2a6614bd80 Add fork, compare, restore CLI commands and fix compare correctness ... Round 2 of the agent handoff dogfood showed that every multi-branch operation required reaching past the CLI into curl: fork had no CLI command, `smriti checkpoint create` always spawned a fresh session with no way to attach to a forked one, and the compare endpoint returned useless output (common_ancestor_commit_id was missing from the response, and shared-set matching was exact-string so two agents phrasing the same commitment differently showed zero overlap). This ships the full CLI surface for multi-branch workflows plus the backend fixes that make compare actually useful: smriti fork <checkpoint-id> [--branch <name>] smriti restore <checkpoint-id> smriti compare <checkpoint-a> <checkpoint-b> smriti checkpoint create <space> --session <session-id> The compare endpoint now walks parent chains to compute a lowest common ancestor (bounded to 1000 steps with a cycle guard) and returns it on CheckpointDiff as an optional uuid. Shared-set matching uses a lightweight lowercase + punctuation-strip + whitespace-collapse normalization for keying, but returns the original A-side strings so the output stays readable. Four new compare tests cover direct and two-step LCA, null LCA for unrelated checkpoints, and normalized shared-set matching. Existing compare tests still pass unchanged because their data ("Use Redis" vs "Use Postgres") is distinct at any sensible normalization level. `smriti restore <checkpoint>` is a pure read — it renders any checkpoint as a continuation brief matching `smriti state <space>` shape. `smriti fork` derives the space from the checkpoint so the user does not have to pass it separately. `--session` on checkpoint create is purely additive: when absent, the existing auto-session behavior is unchanged. 147/147 backend tests pass (143 pre-existing + 4 new).		2026-04-11 17:50:03 +05:30
