docs: correct rust workspace crate count to 11

[nankingjing]

Summary

Follow-up doc fix after #3268.

The Stats section of rust/README.md states 9 crates in the workspace, but the workspace (members = ["crates/*"]) now contains 11 crates:

api, claw-analog, claw-rag-service, commands, compat-harness, mock-anthropic-service, plugins, runtime, rusty-claude-cli, telemetry, tools

(verified by counting rust/crates/*/Cargo.toml — 11 manifests). This PR updates only that number; it does not restructure the layout or responsibilities sections.

Note on a second candidate fix (not included)

While investigating I also checked the reported broken link in how_to_run.md ([futute.md](futute.md)). I did not change it: neither futute.md nor a correctly-spelled future.md exists anywhere in the repository, so retargeting the link would not resolve to a real file. Left untouched pending a decision on whether that target doc should be created.

Good catch — docs that say one thing while the workspace defines another are a real source of confusion for new contributors. With 11 crates now, are you planning to document what the 11th is separately or leave it self-explanatory from the workspace layout?

[nankingjing]

The workspace uses members = ["crates/*"] so any directory dropped under rust/crates/ automatically becomes a member — there isn't really a single 11th crate, the count just drifted from 9 to 11 over time. All 11 are listed in the PR description (api, claw-analog, claw-rag-service, commands, compat-harness, mock-anthropic-service, plugins, runtime, rusty-claude-cli, telemetry, tools). I figured that plus the glob pattern makes it self-explanatory. Happy to add a one-liner listing them in the README if you think it'd help though.
