About: contributor and model credits compiled in (grab bag + table, self-submitted names) (#3)

* About: contributors compiled in from contributors.json (grab bag + table, sortable, name toggle)

Adds the craftrules standard (standards/contributors.md) to DeckCraft's About window:
tabs About · Contributors · Models. contributors/contributors.json is generated by
craftrules/scripts/contributors.py and baked into the binary by crates/ui-egui/build.rs as
static tables. Each contributor line: @username, opt-in display/real name, PRs, commits,
lines +/−/Δ, binary assets +/−, first/last commit. Sortable by every column; alphabetical
ignores case and the leading @. The control channel's ui.dialog.open now honours its
documented `fields` param (e.g. About {"tab": "contributors"}).

* Contributors: self-submitted names in contributors/people.toml; AGENTS.md credit-yourself section

build.rs reads contributors/people.toml next to the generated contributors.json and shows a name only
for entries the generator verified as written by that person (craftrules standards/contributors.md).

+# Contributors in the About window
+
+**About ▸ Contributors** credits everyone who contributed to DeckCraft, and **About ▸ Models** credits
+the AI models named in `Co-Authored-By` trailers. This follows the shared craftrules standard
+[`standards/contributors.md`](https://github.com/storytold/craftrules/blob/main/standards/contributors.md);
+this page is the local copy of the decision.
+
+## Decision
+
+- Two files, both **compiled into the binary** by the UI crate's `build.rs` (nothing is read from
+  disk or the network at run time; the web build has them too):
+  - [`contributors/contributors.json`](../contributors/contributors.json): commit stats per GitHub
+    username. **Generated** by `craftrules/scripts/contributors.py`; never hand-edit.
+  - [`contributors/people.toml`](../contributors/people.toml): the names people chose for
+    themselves. **Each contributor adds only their own entry**, in their own PR.
+- Each contributor gets one line: GitHub username (always), display name (opt-in, or their synced
+  GitHub profile name), real name (only if they told us), merged PRs, commits, lines added, lines
+  deleted, binary assets added, binary assets removed, first and last commit date.
+- The list is shown as a **grab bag** (names flowing as text) or a **table**, in the same order. It
+  sorts by name, PRs, commits, lines added, lines deleted, line delta, binary assets added/removed,
+  first or last commit date. The name toggle cycles **Username → Display name → Real name**; a
+  missing name falls back to `@username`. Alphabetical sorting is case-insensitive and ignores the `@`.
+
+## In DeckCraft
+
+- The About window is the `"about"` dialog in `crates/ui-egui/src/dialogs.rs`; its `tab` field (`about`, `contributors`, `models`) picks the tab.
+
+## Credit yourself
+
+Add your entry to `contributors/people.toml` in a PR you commit yourself (every field optional):
+
+```toml
+[people.your-github-username]
+real_name = "Your Name"
+display_name = "Nickname"
+sync_github_name = true   # use the name on your public GitHub profile as display name
+```
+
+or, with craftrules checked out next to `craft-apps/`:
+
+```sh
+python3 ../../craftrules/scripts/contributors.py --add-me . --real-name "Your Name" --sync-github-name
+```
+
+Names show after the next refresh: the script checks that each entry was committed by its own
+user (or by a maintainer with a `consent_source`). Delete your entry to remove your names.
+
+## Refreshing (maintainers)
+
+```sh
+python3 ../../craftrules/scripts/contributors.py .           # regenerate + verify; needs git, Python 3.11+, gh
+python3 ../../craftrules/scripts/contributors.py --check .   # verify people.toml only
+```
+
+Commit the updated `contributors/contributors.json`. Git author names and emails are never recorded.
