Adds scripts/release/check-versions.sh and a `versions` CI job that runs
on every push/PR. Verifies:
- no per-crate Cargo.toml carries a literal version (must inherit the
workspace version)
- npm/deepseek-tui/package.json matches the workspace version
- Cargo.lock is in sync with the manifests
Closes#31.
Add Yahoo Finance quote tool with chart fallback, redesign header widget
with proportional truncation and context bar, refactor footer status strip,
expand test suite to 680+ tests, and fix blocking issues (usize underflow
in header, tempdir leak in finance tests, per-call HTTP client creation).
- Move src/* into crates/tui/src/ to create a proper workspace structure
- Add .claude/ and .trimtab/ directories for Trimtab closed-loop workflow
- Add DEPENDENCY_GRAPH.md and update documentation
- Update Cargo.toml files to reflect new crate dependencies
- Update CI workflows and npm package scripts
- All tests pass, release build works
