Fix typos and broken references across skill docs (#56)

- Fix missing trailing pipe in error-reference.md table header
- Fix wrong reference path in go.md (python -> go determinism-protection)
- Add missing .md extension to testing reference in go/determinism-protection.md
- Fix typos: "Activty" -> "Activity", "accomplised" -> "accomplished", "discourged" -> "discouraged"

 | **Non-determinism** | TMPRL1100 | `WorkflowTaskFailed` in history | Replay doesn't match history | Analyze error first. **If accidental**: fix code to match history → restart worker. **If intentional v2 change**: terminate → start fresh workflow. | https://github.com/temporalio/rules/blob/main/rules/TMPRL1100.md |
 | **Deadlock** | TMPRL1101 | `WorkflowTaskFailed` in history, worker logs | Workflow blocked too long (deadlock detected) | Remove blocking operations from workflow code (no I/O, no sleep, no threading locks). Use Temporal primitives instead. | https://github.com/temporalio/rules/blob/main/rules/TMPRL1101.md |

 ## Overview
 
-The Go SDK has no runtime sandbox. Determinism is enforced by **developer convention** and **optional static analysis**. Unlike the Python and TypeScript SDKs, the Go SDK will not intercept or replace non-deterministic calls at runtime. The Go SDK does perform a limited runtime command-ordering check, but catching non-deterministic code before deployment requires the `workflowcheck` tool and testing, in particular replay tests (see `references/go/testing`).
