docs(fork): link row 8's upstream issue and PR

[bpamiri]

FORK.md only. Row 8 (the MCP call marker, #19) now links its upstream issue cybersonic#133 and PR cybersonic#134 instead of saying the upstream PR is pending. No code change.

rev1-r3 review @ b38c006: APPROVE

Docs only (FORK.md row 8). I checked every claim against upstream:

• feat(mcp): let a module tell an MCP tools/call from a terminal call cybersonic/LuCLI#133 is an open issue and feat(mcp): tell the module that a call came from tools/call cybersonic/LuCLI#134 an open PR.
• feat(mcp): tell the module that a call came from tools/call cybersonic/LuCLI#134's base is upstream main @ 988073f.
• Its two commits are cherry-pick -x of feat(mcp): tell the module that a call came from tools/call #19's bc31640 and cb203d6, the latter without its FORK.md change.
• FORK.md is not among feat(mcp): tell the module that a call came from tools/call cybersonic/LuCLI#134's files.

The release-order note is unchanged.
