Fix CI failure: add CKB 0.205.0 to download versions

[Copilot]

make prepare was failing because prepare.sh copies download/0.205.0/ckb-cli, but download.py only downloaded versions up to 0.204.0, so that directory never existed.

Changes

• download.py: Added "0.205.0" to the versions list to ensure the 0.205.0 binary (including ckb-cli) is fetched before prepare.sh runs.

versions = [
    "0.200.0",
    "0.201.0",
    "0.202.0",
    "0.203.0",
    "0.204.0",
    "0.205.0",  # added
]

prepare.sh already referenced download/0.205.0/ckb-cli and required no changes.

Original prompt

Problem

The ci_integration_tests workflow is failing at the make prepare step with:

cp: cannot stat 'download/0.205.0/ckb-cli': No such file or directory
make: *** [Makefile:12: prepare] Error 1

Root Cause

There is a version mismatch between what download.py downloads and what prepare.sh / framework/test_node.py expect:

1. download.py (line 14-20): Downloads CKB versions 0.200.0, 0.201.0, 0.202.0, 0.203.0, 0.204.0 — but does NOT include 0.205.0.
2. prepare.sh (line 7): Copies from download/0.203.0/ckb-cli — this is outdated and should reference 0.205.0.
3. framework/test_node.py (line 49-54): Already references download/0.205.0 as CkbNodeConfigPath.CURRENT_TEST, confirming 0.205.0 is the intended current version.

Required Fix

1. download.py: Add "0.205.0" to the versions list so the CKB binary (including ckb-cli) for version 0.205.0 gets downloaded during make prepare.

2. prepare.sh: Update line 7 from:

   cp download/0.203.0/ckb-cli ./source/ckb-cli
   

   to:

   cp download/0.205.0/ckb-cli ./source/ckb-cli
   

   This ensures prepare.sh copies the ckb-cli binary from the correct version directory that matches what framework/test_node.py expects.

Files to modify

• download.py — add "0.205.0" to the versions list
• prepare.sh — change download/0.203.0/ckb-cli to download/0.205.0/ckb-cli
