docs: drop two stale files, correct the two the README links, cut sharp edges

README: "Known sharp edges" removed.

docs/GRAPH_VIEW.md pointed the graph's one backend call at
server/patch_server.py, a file the port deleted. It is
idatui/codemode_client.py now. This matters because GRAPH_VIEW.md is one of
only two docs the README links -- a wrong path in a linked doc is worse than
no doc.

docs/RPC.md was missing five verbs rpc.py serves: ping/methods/quit (now a
Session table) and trace/binaries/switch (with the semantic verbs). The trace
verb drives a whole feature the README advertises, so its absence was the real
gap. Every verb in rpc.py's METHODS table is now documented, checked
mechanically -- the remainder of what looked missing turned out to be values
of the "move" verb's dir parameter, not verbs.

Deleted:

- docs/CODEMODE_PORT.md. Written mid-port, and its Result section claims the
  port covered "the complete current TUI feature set". It did not: the graph
  view was dead, the operand-format keys were dead, pseudocode comments never
  appeared, and bulk rename was broken. Keeping a doc that states the opposite
  of what we found is worse than having none, and docs/CODEMODE_UPSTREAM.md
  carries the accurate account of the API limits.
- docs/TUI_DRIVING_BLUEPRINT.md. A design sketch for generalizing the
  drive-a-TUI-over-a-socket pattern to other programs, with gdb as the main
  example -- which now exists for real in ~/dev/gdb-driver. Superseded by the
  thing it proposed.

Nothing linked either file. Both remain in git history.
