refactor(crates): rename workspace members to codewhale-*

Rename the 14 workspace member crates from `deepseek-*` (and
`deepseek-tui-*`) to `codewhale-*`. Internal-only — binary names
(`deepseek` and `deepseek-tui`) are intentionally untouched in this
phase; they move in the next phase along with the deprecation shims.

Affects:
- 14 `[package] name = "..."` declarations.
- All inter-crate `[dependencies]` entries that referenced the old
  package names.
- All `use deepseek_*::...` statements rewritten to `use codewhale_*`.
- Cargo.lock regenerated.

CI workflows and release scripts that pass `-p deepseek-*` still
reference the old names; those move with the binary rename phase so
that pair lands together.

Local gates green: `cargo check --workspace --all-targets --locked`,
`cargo fmt --all -- --check`, `cargo clippy --workspace --all-targets
--all-features --locked -- -D warnings`, `cargo test --workspace
--all-features --locked` (3226+ pass, 0 fail).
