Extract clemitui into standalone repository (#105)

* docs: add missing details to CLAUDE.md

Document config.toml fields, clemitui demo binary, MSRV 1.88,
cargo-nextest usage, and cargo doc CI gate.

* refactor: extract clemitui into standalone repo

Move clemitui from crates/clemitui/ to evansenter/clemitui as an
independent GitHub repository. clemini now references it as a git
dependency instead of a workspace path dependency.

No functional changes - all 283 tests pass, clippy clean.

* Address PR feedback: commit Cargo.lock, remove workspace, add changelog

- Commit Cargo.lock for reproducible builds (removed from .gitignore)
- Remove single-member workspace wrapper from Cargo.toml
- Add changelog entry for clemitui extraction
- Update CI workflow to remove --workspace flags

* docs: fix stale --workspace flag in CLAUDE.md

Remove --workspace from cargo doc command in quality gates section
to match actual CI workflow after workspace removal.

It takes primitive types (strings, durations, token counts), not genai-rs types, so it can work with any ACP agent. clemini's `format.rs` and `logging.rs` re-export clemitui's API and add genai-rs-specific wrappers.

 These use `validate_response_semantically()` from `tests/common/mod.rs` - a second Gemini call with structured output that judges whether responses are appropriate. This provides a middle ground between brittle string assertions and purely structural checks.
 
 **Shared test helpers** - Common patterns for test utilities:
-- Put shared helpers in `tests/common/mod.rs` (for clemini) or `crates/clemitui/tests/common/mod.rs` (for clemitui)
