fix(openclaw): separate task cwd from agent workspace in system prompt

[btc69m979y-dotcom]

Summary

• add a version-scoped OpenClaw patch that passes the task runtimeCwd through normal runs and compaction
• replace the legacy single-workspace prompt with explicit task-directory and agent-workspace roles only when those paths differ
• preserve persistent memory/profile writes in the agent workspace, existing sandbox behavior, and prompt-cache isolation
• document the source/community research and add patch contract plus strong source-sentinel validation

Verification

• npm test -- taskCwdSystemPrompt
• npm run compile:electron
• npx eslint --ext ts,tsx --report-unused-disable-directives --max-warnings 0 src/main/libs/openclawPatches/taskCwdSystemPrompt.test.ts
• OpenClaw targeted Vitest: 3 files, 96 tests passed
• OpenClaw oxfmt --check on the 7 touched source/test files
• reverse git apply --check against the locally applied OpenClaw source

Electron / OpenClaw impact

This changes the bundled OpenClaw system prompt after the runtime is rebuilt. It does not change IPC, SQLite, OpenClaw config shape, workspace locations, or memory-flush storage behavior.

The full patch-reset command was not run because the sibling OpenClaw checkout contains unrelated uncommitted work and that command resets the checkout. The generated patch was instead reverse-checked against the applied source and covered by LobsterAI source sentinels.
