* Build each crate's integration tests as one binary
Every tests/*.rs file is its own executable that links the whole crate
graph. Move each crate's test files into tests/it/ as modules of one
tests/it/main.rs, for apps/pdfcraft, apps/pdfcraft-cli, automation, cos,
crypt, engine, render, sign and ui-egui. ui-egui's ui_group binary and
the support modules move into tests/it/ too. Crates with a single test
file keep it. The test executables go from 150 to 52, and every crate
runs the same number of tests as before.
ui-egui perf keeps its own binary (own process): its frame-time budgets
would charge each measurement for the other tests running beside it.
What the move needs:
- include_str!/include_bytes! and #[path] paths gain one "../".
- ui-egui: one GPU lock in tests/it/main.rs replaces the five per-file
ones (content, document_links, editing, fill_sign, view), so one
process creates one wgpu device at a time. The drop-line test in ui.rs
and the screenshot blocks behind PDFCRAFT_*_SHOT(S) and
CRAFT_UI_DOCKING_DIR, which render without holding it, take it too.
- pdfcraft winit_wayland_scroll: the vendored winit source it compiles
names crate::event, so that shim lives in main.rs.
- parity evidence names the new paths.
* Name the one-binary test paths in docs and comments
- READMEs, docs, ATTRIBUTION and source comments name tests/it/<file>.rs.
- The oracle README's example filters with --test it encryption::qpdf_agrees.
- pdfcraft's GPU lock comment points at the UI tests' shared lock in
crates/ui-egui/tests/it/main.rs.
