 - Lint: `cargo clippy --workspace --all-targets --all-features`
 - Format: `cargo fmt --all`
-- Run (canonical): `deepseek` — use the **`deepseek` binary**, not `deepseek-tui`. The dispatcher delegates to the TUI for interactive use and is the supported entry point for every flow (`deepseek`, `deepseek -p "..."`, `deepseek doctor`, `deepseek mcp …`, etc.).
-- Run from source: `cargo run --bin deepseek` (or `cargo run -p deepseek-tui-cli`).
-- Local dev shorthand: after `cargo build --release`, run `./target/release/deepseek`.
-- **Two binaries, two installs.** `deepseek` (the CLI dispatcher, `crates/cli`) and `deepseek-tui` (the TUI runtime, `crates/tui`) ship as **separate executables**. The dispatcher resolves and spawns `deepseek-tui` as a sibling on PATH for interactive use, so installing only the CLI leaves the TUI stale and your fix won't appear to run.
