1.2.0: Shared Assets folder, git commit policy, history discipline

Add a flat TandemKit/NNN-MissionName/Assets/ folder that both the
Generator and the Evaluator write into. Filenames encode round, role,
and slug (R01-Gen-Before-en.webp, R02-Gen-After-en.webp,
R01-Eval-ClickTransition.webp); locale-specific captures append a
dash plus the BCP-47 2-letter code (-en, -de, -ja, …), never a
spelled-out language name. The Evaluator reads the Generator's
captures as primary evidence for visual criteria and only re-captures
when the existing file is insufficient. The Generator's PR-description
template reuses the same files for before/after tables so nothing is
captured twice. create-mission.sh scaffolds the folder at mission
start; Config.json gains a namingConvention field that casing follows.

Replace the yes/no gitignore toggle in /tandemkit:init Question 7 with
a three-option git commit policy: commit everything, commit text only
(default, recommended), or don't commit TandemKit at all. The choice
is stored in Config.json as git.tandemKitCommit ("all" / "text-only" /
"none") and Step 7 of init writes the matching .gitignore entries. The
Generator's PR-description guidance branches on the same value so
committed assets link via raw URL and uncommitted assets are
drag-dropped into the PR body for GitHub upload.

Add a Commit Messages & PR Text section to the Generator skill. Commit
titles, commit bodies, PR titles, and PR descriptions describe what
changed and why, never how it was developed — TandemKit, the role
names, missions, rounds, R01/R02 tags, and FAIL/PASS iterations stay
out of externally visible history. One explicit exception: the
optional post-mission commit of the TandemKit/NNN-MissionName/ text
files may reference "mission files" in its subject. Project-specific
Generator.md / Evaluator.md may override the rule. Question 4 of the
init flow surfaces the rule at setup time.

+
+| Option | What's committed | When to pick it |

+| **All** | Coordination text + binary assets (screenshots) | Projects where UI/visual missions are common and you want PR descriptions to link screenshots via GitHub's raw URL. Full audit trail. |
+| **Text-only** (default) | Coordination text; assets gitignored | Good for most projects — you keep the full textual history (decisions, discussions, specs, reports) without bloating the repo with binary captures. Generator can still upload screenshots to PRs manually when needed. |

+**Screenshots & assets.** For missions that produce visual evidence (UI fixes, layout work), both roles save WebP captures to the flat `Assets/` folder with filenames like `R{NN}-Gen-<Slug>.webp` and `R{NN}-Eval-<Slug>.webp` — round + role + slug, casing from the project's `namingConvention` in `Config.json`. When a capture is locale-specific, append a dash plus the 2-letter language code (BCP-47 short form — `en`, `de`, `ja`, …): `R02-Gen-After-en.webp`, `R02-Gen-After-de.webp`. Never spell out language names. Any media type works (extension decides). The Evaluator reads the Generator's captures as primary evidence — a screenshot is a fact about what the UI looked like at that moment — and only re-captures when the existing file is insufficient (element covered, wrong crop, post-interaction state missing). Captures also feed the PR description's before/after images when the Generator opens a PR.

+- **Coordination text files** (`State.json`, `Spec.md`, `Claude-NN.md`/`Codex-NN.md` discussion files, `Generator/Round-NN.md`, `Evaluator/Round-NN.md`, etc.) — small, plain-text, high value as an audit trail of the development history.
+- **Binary assets** (screenshots and other verification artifacts under `NNN-Mission/Assets/`) — typically WebP screenshots written by the Generator and consumed by the Evaluator. They can add up in repo size if every mission keeps many captures.

+- **Commit everything (text + assets)** — full audit trail including before/after screenshots. Enables linking screenshots from PR descriptions via GitHub's raw URL. Best for projects where UI/visual missions are common and the history is worth keeping. Stores `TandemKit/` untouched in git.
+- **Commit text only, gitignore assets (Recommended)** — keeps the full textual audit trail (decisions, discussions, specs, reports) but ignores `TandemKit/*/Assets/` so binary captures don't bloat the repo. Screenshots still live on disk for the active mission; Generator can upload them to a PR separately if needed.
+- **Don't commit TandemKit at all** — everything under `TandemKit/` is gitignored. Use if you prefer to keep coordination artifacts out of the repo entirely. The files still exist on disk during the mission.

+## Screenshots as Evidence — Read First, Re-Run If Needed
+
+The Generator saves verification captures to `TandemKit/NNN-MissionName/Assets/` as `R{NN}-Gen-<Slug>.<ext>` (e.g., `R01-Gen-Before-en.webp`). You save yours there too as `R{NN}-Eval-<Slug>.<ext>` when the Generator's aren't sufficient. Filename casing follows `Config.json` → `namingConvention`; locale-specific captures carry a dash + 2-letter code (`-en`, `-de`, `-ja`, …) — never spelled-out language names.
+
+**Screenshots are facts.** A capture at round N is a factual record of what the UI looked like then — the pixels are the evidence, same as a build log. Reading the Generator's `R{NN}-Gen-*` captures is the first-choice evidence path for visual criteria; saves tokens and time.
+
+**Read first when:** the criterion is visual and the relevant elements are clearly shown uncovered by overlays, the file is from the current round, and required variants (locales, modes) are present.
+
+**Re-capture yourself when:** a key element is covered, truncated, or off-crop; the criterion requires interaction and no post-interaction capture exists (cheap MD5 check: `md5 -q R01-Gen-Before.webp R01-Gen-After.webp` — identical = click didn't land); behavior is beyond a static render (animation, focus, scroll); or the file's mtime predates the round's commit. Save yours as `Assets/R{NN}-Eval-<Slug>.<ext>` so the Generator can reference the same evidence from the next round.
+
+Being critical of what's **visible** in a screenshot is correct. Being critical of **whether the screenshot happened at all** is not — it did, and the file proves it.

+**Cite files, don't re-describe.** ✅ "AC 5 — PASS. Card pinned to fixed height, no empty bottom space; verified from `Assets/R02-Gen-After-en.webp` (compare to `R01-Gen-Before-en.webp` where the gap is visible)." ❌ "AC 5 — PASS. The card now has the correct height."
