mkaliezz/dsh-action-ledger: DeepSeek Harness Action Lifecycle Projection

DSH Harness (DSH) persists action facts to logs. The `dsh-action-ledger` plugin uses the `/action-ledger` command to read and reconstruct these facts into a readable timeline. It projects the lifecycle of tool calls (from request to success or failure), guarantees deterministic ordering, but does not copy parameters or create custom event types. This tool provides only a read-only view for debugging and auditing; it does not replace persistence or authorization systems, nor does it prove physical side effects, and DSH’s developer-preview compatibility should be noted.
