test(#139): improve cmd/review-bot coverage from 44.6% to 49.3%

Add tests for previously uncovered paths:

- TestIsValidateError_Nil: isValidateError(nil, ...) returns false
- TestValidateURL_EmptyHost: URL with no hostname (https://) → code-2 error
- TestRunValidateURL_Success: success path (OK output + exit 0) via example.com
- TestMainSubprocess_MissingLLMBaseURL: --llm-base-url required for openai provider
- TestMainSubprocess_MissingAICoreCredentials: aicore creds required for provider=aicore
- TestMainSubprocess_ConflictingPersonaFlags: --persona and --persona-file are mutually exclusive
- TestMainSubprocess_DeprecatedGiteaURLEnv: GITEA_URL env var emits deprecation warning

All tests pass; no production code changes; dep check clean.

-## Subcommands
-
-### `validate-docmap`
-
-Verifies that a `doc-map.yml` is consistent before running a review. Two checks:
-
-1. **Coverage**: every changed file is matched by at least one `paths:` glob.
-2. **Stale docs**: every `docs:` entry exists on disk under `--repo-root`.
-
-```bash
-# Typical CI usage — pipe git diff into the command
-git diff --name-only origin/main HEAD | \
-  review-bot validate-docmap \
-    --docmap .review-bot/doc-map.yml \
-    --repo-root .
-```
-
-| Flag | Required | Default | Description |
-|------|----------|---------|-------------|
-| `--docmap` | Yes | — | Path to doc-map YAML file |
-| `--repo-root` | No | `.` (cwd) | Root for resolving `docs:` paths |
-
-Exit codes: `0`=clean, `1`=failures found, `2`=usage/parse error.
-
-### `validate-url`
-
-Resolves a URL and verifies all IPs are publicly routable (used in CI to prevent SSRF).
-
-```bash
-review-bot validate-url https://gitea.example.com
-```
-
-Exit codes: `0`=safe, `1`=blocked/private IP, `2`=error.
