README CLI section claims "eight subcommands" but ships nine (missing suggest)

Fixes #190

REQUEST_CHANGES

The count fix ("eight" → "nine") is correct, but the PR does not meet either acceptance criterion from #190:

1. Broken example block — the added line (Now for the missing \suggest` example in the code block:) is inserted inside the ```bash ` fenced block. It renders as a shell command, corrupting the README.
2. No suggest example — the issue explicitly requires a chainweaver suggest <flow> entry in the example block with a one-line description. None was added.

Suggested fix — replace the two added lines with:

# Get improvement suggestions for a flow (CW001–CW004 families).
chainweaver suggest flows/etl.flow.yaml --tools my_pkg.tools

See inline comment for the exact location.

Blocker — prose inside a bash fenced block

The added line renders as a shell command inside the code block, which corrupts the example. The issue acceptance criteria require a real suggest command example following the established pattern:

# Brief description comment
chainweaver <cmd> <args>

Replace both added lines (the blank and this prose) with something like:

# Get improvement suggestions for a flow (CW001–CW004 families).
chainweaver suggest flows/etl.flow.yaml --tools my_pkg.tools
