Conflict between reduction and filesystem middleware

**Describe the bug**

1. Tool call returns a long _single_ line rather than multiline content
2. Gets truncated/off-loaded
3. read_file on the content
4. read_file response is then truncated once again
5. loops

The reduction middleware may truncate or completely offload content to a file which the agent then makes use of the filesystem middleware to read said truncated/off loaded content. If this content is a single long line, then no amount of filesystem.Read() will work, the agent will be stuck in a loop.

**To Reproduce**

Steps to reproduce the behavior:
1. Add recommended middleware(s)
2. CM response with a very long single line
3. Tool gets truncated
4. Agent reads file with contents
5. Output is truncated

**Expected behavior**

(a) read_file result to NOT have the same redaction message **(do not re-offload it)**
(b) read_file to consider content with long single lines (aka: columns not just lines)

**Additional context**

The [middleware recommendations](https://www.cloudwego.io/docs/eino/release_notes_and_migration/eino_v0.8._-adk_middlewares/#middleware-usage-recommendations) only work well when a model has reasoning content. The reasoning content gets held back and then the model can understand even though the content has been off-loaded or redacted. This should probably be mentioned, along with some configuration examples for different cases.

Alternatively, a scratchpad can be added for the agent to note down important things (which should not get redacted) but I've found this to be so-so but that might just be my prompting.

**EDIT:** I've also noticed that the off-loaded content is in `json` rather than just the content of the tool output. I'm not sure if this is intentional. I believe this is also adding to the single line issue as the json takes the content from multi line to single line (Obviously ignoring the fact that some tool somewhere may still return a very long line that these tools should account for)

**EDIT2** It also keeps re-adding line numbers when off-loading the read file. See example:
```json
