Docs show "--platform claude-code" but CLI only accepts "--platform claude"

[AR6420]

Environment:

• code-review-graph: latest (pip install)

Bug:
The README shows:

code-review-graph install --platform claude-code

But running this gives:

error: argument --platform: invalid choice: 'claude-code' 
(choose from claude, cursor, windsurf, zed, continue, opencode, antigravity, all)

The correct command is --platform claude.

Expected behavior:
Either:

1. Update the README to show --platform claude (simple docs fix), or
2. Add claude-code as an alias in the CLI so both work (better UX since users may copy-paste from the README)

Fixed via PR #78 — --platform claude-code is now accepted as an alias for --platform claude.

Checking current CLI for --platform flag values.

Confirmed fixed: --platform claude-code is now a valid option (cli.py choices include 'claude-code'). Issue correctly closed.
