Fixes #5229: Profile Condense Threshold not working

[roomote]

Summary

This PR fixes GitHub issue #5229 where profile-specific condensation thresholds were not working correctly.

Problem

When users set a condensation trigger threshold (e.g., 25%) for a specific profile in Settings->Context->Condensing Trigger Threshold, the automatic context condensation would not trigger at the specified threshold. Instead, it would fall back to the global threshold setting.

Root Cause

The bug was in src/core/task/Task.ts at line 1724. The code was using currentApiConfigName (which contains the profile name) as the key to lookup profile thresholds, but the profileThresholds object is actually keyed by profile ID. This mismatch meant the profile-specific threshold was never found.

Solution

• Fixed the profile ID lookup by properly resolving the profile ID from the profile name
• The fix searches through listApiConfigMeta to find the matching profile configuration and extract its ID
• Added a comprehensive test case that reproduces the original issue and verifies the fix works correctly

Changes

• src/core/task/Task.ts: Fixed profile ID resolution logic in truncateConversationIfNeeded
• src/core/sliding-window/tests/sliding-window.spec.ts: Added test case for GitHub issue Profile Context Condense Threshold not working #5229

Testing

• All existing tests continue to pass
• New test specifically reproduces the issue scenario and confirms the fix works
• Verified that profile-specific thresholds are now properly applied instead of falling back to global defaults

Closes #5229

Important

Fixes profile-specific condensation threshold lookup in Task.ts by resolving profile ID correctly, with tests added to verify the fix.

• Behavior:
  • Fixes profile-specific condensation threshold lookup in truncateConversationIfNeeded in Task.ts by resolving profile ID from profile name.
  • Ensures profile-specific thresholds are applied instead of falling back to global defaults.
• Testing:
  • Adds test case in sliding-window.spec.ts to verify profile ID resolution and correct threshold application.
  • Confirms that profile-specific thresholds trigger condensation as expected.
• Misc:
  • Closes GitHub issue Profile Context Condense Threshold not working #5229.

I think the solution on #5230 is a bit cleaner, however feel free to reopen if necessary.
