fix: query validation, body read error, HTML escaping, profile sorting (#58-62) (#38)

## Summary
- **#58**: `raw --query` now rejects empty keys (e.g. `--query "=value"`
produced `?=value` in URL)
- **#59**: `fetchJSONWithBody` propagates `io.ReadAll` errors instead of
silently returning empty body on read failure
- **#60**: Schema, workflow, and configure output uses
`SetEscapeHTML(false)` to preserve literal `&`, `<`, `>` characters
(previously `json.Marshal` escaped `&` to `\u0026`)
- **#61**: `configure --test` sorts available profile names for
deterministic error messages
- **#62**: Fix pre-existing lint `errcheck` warnings in test files

## Test plan
- [x] New e2e test: `TestE2E_Raw_QueryEmptyKey` — verifies empty key
rejected
- [x] New unit test: `TestFetchJSONWithBody_ReadError` — verifies body
read errors are propagated
- [x] New e2e test: `TestE2E_Schema_NoHTMLEscape` — verifies `&` not
escaped to `\u0026`
- [x] New e2e test: `TestE2E_Configure_TestProfilesSorted` — verifies
sorted profile list
- [x] New e2e test: `TestE2E_Workflow_OutputNoHTMLEscape` — verifies
transition names with `&` preserved
- [x] New unit test: `TestMarshalNoEscape_PreservesSpecialChars` —
verifies helper function
- [x] All existing tests pass
- [x] Linter passes clean
