fix: correct typo in terminal ReadFile output message

[mason5052]

Description of the Change

Problem

The ReadFile() method in terminal.go displays a header for each file when reading a directory:

'filename' file content (with size N bytes) keeps bellow:

This contains a typo: "bellow" means "to shout loudly" (as in a bull bellowing). The intended word is "below" (underneath). The phrase "keeps below" is also awkward -- "shown below" is clearer.

Solution

Changed "keeps bellow" to "shown below" on line 300 of terminal.go.

Type of Change

• Bug fix (non-breaking change which fixes an issue)

Areas Affected

• Core Services (Backend API / Workers)

Testing and Verification

Test Configuration

PentAGI Version: v1.2.0 (master @ e97bbe5)
Docker Version: N/A (single-line string change)
Host OS: Windows 11
LLM Provider: N/A

Test Steps

1. Verified the typo exists on current master (line 300)
2. Changed "keeps bellow" to "shown below"
3. Verified no other occurrences of "bellow" in the codebase

Test Results

• String-only change, no logic affected
• No test breakage (the output string is not asserted in any test)

Security Considerations

No security impact. This is a cosmetic fix to a user-facing output string.

Performance Impact

None.

Documentation Updates

• README.md updates
• API documentation updates
• Configuration documentation updates
• GraphQL schema updates
• Other

No documentation changes required.

Deployment Notes

Backward-compatible. No configuration changes needed.
