debug: green-eye wave 2 - injection SDK, Frida-like calls, Ghidra control bridge, long-term docs

Adds to debug/risc-v-gsp-rm-vm/:
- Session.call / run_until: Frida-like remote function calls and run-to-cursor,
  with register restoration; verified live (rpc_ping -> 0xaffe).
- symbol+offset target resolution (gsp_ctrl+0x10) across all APIs and the REPL.
- Injection SDK (sdk/) and 'greeneye inject': position-independent RV64 service
  blobs (verified zero relocations), loaded into RAM, registered in the demo
  handler table, and invoked either directly or through the firmware mailbox
  dispatcher. Demo ABI extended: mailbox 16..23 selects slots, arg0 carries the
  service command, arg2 added (struct now 0x190; schema updated).
- Ghidra control bridge (greeneye ghidra + GreenEyeControl.java): run-until-here,
  breakpoints, memory/register access, remote calls, hit export; verified
  end-to-end with Ghidra headless (run_until reached rpc_sum from a GhidraScript).
- MarkGreenEyeHits.java fixed for the Ghidra 12 createBookmark API; verified
  headless together with ExportForGreenEye.java.
- Analyzer renders a QEMU first-fault table for probe sessions (fault count,
  epc with firmware vaddr translation, access address/size, reason).
- Tests now 35 green, including injection, Ghidra bridge, remote call, run-until
  and REPL command smoke tests.
- Documentation: docs/11-16 (GSP RM service developer guide, injection SDK
  specification, Ghidra control, adversarial interoperability guide, agentic
  GSP IDE, custom simulator design) and GREEN-EYE-ROADMAP.md (long-term H1-H7
  program); doc maps and the project RISC-V VM doc updated.
