fix(daemon): preserve backslashes in parseCommandLine on Windows (#15642)

* fix(daemon): preserve backslashes in parseCommandLine on Windows

Only treat backslash as escape when followed by a quote or another
backslash. Bare backslashes are kept as-is so Windows paths survive.

Fixes #15587

* fix(daemon): preserve UNC backslashes in schtasks parsing (#15642) (thanks @arosstale)

@@ -13,6 +13,7 @@ Docs: https://docs.openclaw.ai
 - Agents/Image tool: cap image-analysis completion `maxTokens` by model capability (`min(4096, model.maxTokens)`) to avoid over-limit provider failures while still preventing truncation. (#11770) Thanks @detecti1.
 - TUI/Streaming: preserve richer streamed assistant text when final payload drops pre-tool-call text blocks, while keeping non-empty final payload authoritative for plain-text updates. (#15452) Thanks @TsekaLuk.
 - Inbound/Web UI: preserve literal `\n` sequences when normalizing inbound text so Windows paths like `C:\\Work\\nxxx\\README.md` are not corrupted. (#11547) Thanks @mcaxtr.
+- Daemon/Windows: preserve literal backslashes in `gateway.cmd` command parsing so drive and UNC paths are not corrupted in runtime checks and doctor entrypoint comparisons. (#15642) Thanks @arosstale.
 - Security/Canvas: serve A2UI assets via the shared safe-open path (`openFileWithinRoot`) to close traversal/TOCTOU gaps, with traversal and symlink regression coverage. (#10525) Thanks @abdelsfane.
 - Security/Gateway: breaking default-behavior change - canvas IP-based auth fallback now only accepts machine-scoped addresses (RFC1918, link-local, ULA IPv6, CGNAT); public-source IP matches now require bearer token auth. (#14661) Thanks @sumleo.
 - Security/Gateway: sanitize and truncate untrusted WebSocket header values in pre-handshake close logs to reduce log-poisoning risk. Thanks @thewilloftheshadow.
