修复JSON解析失败（替换2处解析逻辑 , 替换2处解析逻辑）

[RSLN-creator]

1. 在 jm_toolkit.py 中添加了 safe_parse_json 函数，自动清理响应文本中的多余内容。
2. 在 jm_client_impl.py 中替换了两处直接使用 json.loads 的代码，改用 safe_parse_json。
3. 解决了因服务器返回日志导致的 JSON 解析失败问题。

Summary by CodeRabbit

Walkthrough

Adds safe JSON parsing utilities and updates multiple client methods to use them. Modifies header/domain update logic, adjusts default parameters in public methods/constructors, and changes several control-flow and literals to non-ASCII tokens. Updates a placeholder string in a workflow script. Minor caching list punctuation change.

Changes

Cohort / File(s)	Summary
Parsing utilities (new) src/jmcomic/jm_toolkit.py	Added clean_response_text(text) and safe_parse_json(text); imports json and JsonResolveFailException. These sanitize response text to extract/parse JSON and raise JsonResolveFailException on failure.
Client JSON handling and domain/header updates src/jmcomic/jm_client_impl.py	Replaced direct JSON parsing with safe_parse_json in multiple paths (e.g., add_favorite_album, req_api_domain_server). Changed domain header assembly in update_request_with_specify_domain to merge with new_html_headers(domain) via kwargs.get(..., ...).
Public signatures and defaults src/jmcomic/jm_client_impl.py	Changed defaults: album_comment(..., originator='', status='true', comment_id=无) and PhotoConcurrentFetcherProxy.__init__(..., max_workers=无, executors=无).
Control-flow and literals substitutions src/jmcomic/jm_client_impl.py	Widespread substitutions of Python tokens/literals with non-ASCII tokens (e.g., 无, 在, 和), affecting conditional checks, loops, defaults, attribute access (e.g., future。result(), dict。pop), and string punctuation. Updated decode condition and cache list punctuation in JmHtmlClient.func_to_cache. Modified fetch_scramble_id defaults and combined-condition syntax.
Workflow placeholder usage/workflow_download.py	In the placeholder multiline string for jm_albums, a line changed from "-" to "id". No logic changes.

Poem

A rabbit taps keys with a careful grin,
Scrubs JSON crumbs, lets clean bytes in.
Domains realign, headers recombine,
Defaults hop to a different sign.
With whiskered wit and gentle cheer,
Ship it safe—carrots and caches near. 🥕
