Tapped hole: thread every piece of a wall split by a pocket or slot (#13505 )

A tapped hole drilled across a pocket or slot leaves its cylindrical wall in separate faces along the axis. The thread was put on only the piece nearest the entry, so cosmetic and modelled threads stopped at the first gap. The hole now threads every piece of the wall within its depth, and a thread depth runs on through the pieces from where the first one starts. Fixes #13505 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Hole: a counterbore sized to the screw's head, from clearance and head (#12321 ) (#12322 )

+Colour rules and data that any crate may share. It has no dependencies and holds no app types,

+colours instead of keeping copies.
+
+The sRGB transfer function (IEC 61966-2-1) lives here once: every encode and decode in Rust goes
+through `srgb`, so a change to the rule is one change. Shaders can't call Rust and keep their own
+copies.

+The control channel any app may share (docs/control-protocol.md). An app that listens for
+control makes a random token per launch, writes it to a file only the user can read and refuses
+every connection whose first request doesn't carry it; a client finds the token the same way.
+Which app the files belong to, its environment, its name in messages and its default port come
+from an `App` value the app defines. No app types and no engine.

+| `App::write_current_port`, `App::read_current_port`, `App::remove_current_port` | The discovery file of the most recently started app |
+| `App::env_token()`, `App::client_token(port, explicit)` | The token a client sends: explicit, `CONTROL_TOKEN`, else the token file |
+| `auth::ClientToken::explain_error(error)` | A refusal with the token file named and whether it is stale; never the token |
+| `auth::plan`, `auth::Listen`, `auth::bind_with_fallback`, `auth::PORT_TRIES` | Where a launch listens; a loopback listener on the first free port |
+| `auth::tokens_match`, `auth::remove_token_file`, `auth::TokenFile`, `auth::pid_path`, `auth::MIN_TOKEN_LEN` | Constant-time compare and token file housekeeping |
+| `Effect` | What a request still running does when it finishes: reads only, writes a file, or changes; `when_done(document)` says it |
+| `server::Hub`, `server::Protocol`, `server::Summary`, `server::Waits`, `server::new_token` | The loopback JSON-lines server behind the token (desktop only); the app says what its requests mean |
