* fix(coding-agent): use supported Anthropic compaction model
The Anthropic compaction test was pinned to claude-3-7-sonnet-latest, which now fails with a 404 because that model line was retired. Switch the test to the existing claude-sonnet-4-5 convention used elsewhere in coding-agent tests.
* test(coding-agent): disable git prompts in HTTPS parsing test
The HTTPS URL parsing test intentionally clones a nonexistent GitHub repo to verify that bare HTTPS sources dispatch to git. Under a TTY, git can prompt on that path and hang the test run.
Set GIT_TERMINAL_PROMPT=0 in that test so it still exercises real git but fails fast instead of waiting for terminal input.
