test: cover prepareContext validation error branches (#1460)
* test: cover prepareContext validation error branches

create-prompt.test.ts exercised only happy paths; the ~20 validation
guards in prepareContext (missing PR_NUMBER, unsupported event type,
unsupported issue action, missing claude branch, etc.) had no coverage.

Adds a "prepareContext validation errors" block asserting the thrown
messages for the reachable guards, using the existing createMockContext
helper.

* test: cover comments/common link and body builders

`src/github/operations/comments/common.ts` had no direct test coverage,
though its exports are live code used by create-initial.ts and
update-with-branch.ts. This adds unit tests for all four exports:
SPINNER_HTML, createJobRunLink, createBranchLink, and createCommentBody.

Assertions are built from the imported GITHUB_SERVER_URL so they hold on
GHES as well as github.com. Pure test additions — no production changes.
