What does this PR do?

This preserves raw tool input while a legacy v1 tool part is still pending/running.

The bug I hit was observed with OpenCode v1.14.28 on Windows PowerShell. My local Mavis wrapper/log observer is not part of OpenCode, but its logs showed the failure shape as a terminal state mismatch: lastStatus=running while terminal status=completed, followed about 30 minutes later by session.finish reason=stale.

Relevant local Mavis log anchors:

• line 151: [stream-stall] progress ignored without armed state
• line 190: lastStatus=running with status=completed
• lines 729-736: session.finish reason=stale, idleMs=1800408

The local trigger shape was:

New-Item -ItemType Directory -Path $env:TEMP\opencode-pipeline-repro -Force | Out-Null
Get-ChildItem $env:TEMP\opencode-pipeline-repro

On current dev, I reproduced the relevant OpenCode-side state loss with a focused regression test. A clean origin/dev worktree at f52424e05f, with only the regression test applied, failed because the running tool state had raw === undefined while the PowerShell pipeline was still running.

This PR:

• accumulates tool-input-delta text into pending/running raw
• preserves raw, time.start, title, and metadata across pending -> running and running metadata updates
• adds optional raw?: string to legacy v1 ToolStateRunning
• updates OpenAPI/generated SDK types for that optional field
• redacts running raw in sanitized session export
• drops unexpected error-state raw
• keeps running raw in subagent compaction, while keeping error compaction clean

Generated artifacts were regenerated/checked with:

• bun dev generate > ../sdk/openapi.json in packages/opencode
• bun ./packages/sdk/js/script/build.ts at repo root

The generated SDK/OpenAPI content diff is limited to optional raw on ToolStateRunning.

How did you verify your code works?

Environment: Windows. Initial focused verification used Bun 1.3.13. Before pushing, I upgraded local Bun to 1.3.14 to satisfy the repository pre-push hook (packageManager: bun@1.3.14); the hook then ran root bun typecheck successfully.

PowerShell regression prefers powershell.exe, falling back to pwsh only if Windows PowerShell is unavailable. On this machine powershell resolves to C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe, $PSVersionTable.PSVersion = 5.1.26100.8737.

Passing locally:

• bun run typecheck in packages/opencode
• bun run typecheck in packages/sdk/js
• bun run typecheck in packages/schema
• root bun typecheck via the pre-push hook after upgrading to Bun 1.3.14
• bun test test/session/processor-effect.test.ts test/cli/export.test.ts test/cli/run/subagent-data.test.ts --timeout 30000 in packages/opencode
  • 25 pass, 0 fail, 112 expect() calls
• bun test test/session/prompt.test.ts --timeout 30000 in packages/opencode
  • 44 pass, 14 skip, 0 fail, 186 expect() calls
• git diff --check

Full-suite note:

• Earlier local Windows bun test --timeout 30000 in packages/opencode exceeded the 604 second command timeout before producing a complete result.
• I am treating that full-suite Windows timeout as unrelated to this PR.
• I am not claiming it as fixed by this PR, not claiming it as a pass, and not using it as evidence for this raw running-tool-state change.

Screenshots / recordings

N/A; this is a session state handling fix.
