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.

+// GreenEyeControl - drive a live green-eye session from Ghidra.
+//
+// The script connects to the green-eye JSON-lines bridge (start it with
+// `./greeneye.sh ghidra [--kernel <elf>]`), and exposes the operations a
+// reverse engineer needs while reading the decompiler:
+//
+// ping() - check the bridge
+// info() - session name, pc, symbol count, recording path
+// resolve(name) - symbol/expression -> runtime address
+// setBreakpointHere() - software breakpoint at currentAddress
+// setBreakpointAt(addr) / clearBreakpointAt(addr)
+// runUntilHere() - resume and stop when execution reaches currentAddress
+// runUntil(addr) - same for an explicit address (hex string)
+// readMemoryHere(size) - hex bytes at currentAddress
+// readRegister(name) / writeRegister(name, value)
+// callFunction(addr, args) - Frida-like remote call; returns a0
+// snapshotHere(size) - record a memory snapshot in the session
+// listHits() - breakpoint hit counts from the session
+// exportHits(path) - write greeneye_hits.tsv for MarkGreenEyeHits.java
+//
+// Usage (Ghidra headless):
+// analyzeHeadless <proj> <name> -process <program> -noanalysis \
+// -scriptPath debug/risc-v-gsp-rm-vm/ghidra \
+// -postScript GreenEyeControl.java <bridge-port> [address]
+//
+// The optional address argument makes the script run until that address and
+// print the hits; in the GUI, omit it to use the current cursor address.
