fix(memory-tree): rename window_days → time_window_days for query_global

[xinzhuwang-wxz]

Problem

query_global RPC used window_days internally but the JSON schema exposed time_window_days. DeepSeek (and some other providers) pass parameters exactly as named in the schema, causing parse errors:

missing field `window_days`

Solution

• Rename QueryGlobalRequest::window_days to time_window_days
• Update query_global_rpc() to match
• Update tool schema, description, and execute() consistently
• Update RPC test

Testing

• Fixes DeepSeek tool call parse errors
• Existing RPC test passes with renamed field

Summary by CodeRabbit

• Refactor
  • Standardized parameter naming for the global memory query from window_days to time_window_days across retrieval and tool implementations.
• Bug Fixes
  • Increased startup readiness timeout to better tolerate cold-start latency, improving reliability of the embedded core during slow starts.

📝 Walkthrough

Walkthrough

Renames the time-window field from window_days to time_window_days across the RPC request, handler, unit test, and the memory query tool; separately increases the embedded-core readiness polling window from ~4s to ~30s.

Changes

Parameter Rename Across RPC and Tool Boundary

Layer / File(s)	Summary
RPC Request Contract and Handler Update src/openhuman/memory/tree/retrieval/rpc.rs	QueryGlobalRequest struct field renamed from window_days to time_window_days; query_global_rpc now forwards req.time_window_days; unit test updated to use time_window_days: 7.
Tool integration: description, schema, and execution src/openhuman/tools/impl/memory/tree/query_global.rs	Tool description text and parameters_schema() updated to define and require time_window_days; execute() passes req.time_window_days into retrieval::query_global.

Embedded-core readiness timeout tuning

Layer / File(s)	Summary
Tauri core readiness loop app/src-tauri/src/core_process.rs	Increased readiness polling iterations from 40 to 300 (100ms sleeps) and updated comments to reflect new ~30s stuck timeout for embedded-core startup.

Poem

🐰 I hopped through code to make a change,
A field renamed — not wild, just strange.
From window_days to time_window_days I leapt,
And waited longer while the core slept.
Small tidy hops, the tree now sings.

huge thanks @xinzhuwang-wxz, nailing that window_days → time_window_days rename so deepseek (and friends) stop choking on the schema is such a clean catch 🙌. love seeing you back in here, this one's gonna save folks a lot of confused debugging.
