docs: add English README for project-bootstrap; translate root README

- skills/project-bootstrap/README.md: new English README (modes,
  triggers, prerequisites, layout, install, see-also).
- README.md: translated to English; both root READMEs cross-link.
- README.ru.md: original Russian preserved (renamed from README.md);
  fixed broken `.wiki/source/repo-layout.md` link to point at the real
  path under `.wiki/concepts/`.

+# project-bootstrap
+
+Initializes or upgrades a project workspace in one pass: git, `.gitignore`,
+`README.md`, `.wiki/` (Karpathy's LLM Wiki layout), `.tasks/` (per-task board),
+and `CLAUDE.md` with skill triggers.
+
+Operates in two modes, picked automatically:
+
+- **init** — empty or near-empty folder. Creates everything from scratch.
+- **upgrade** — existing project. Detects what's already there, only fills the
+  gaps. Never overwrites without explicit confirmation.
+
+## When it triggers
+
+The skill auto-activates on phrases like:
+
+- "initialize project", "bootstrap", "setup project"
+- "upgrade project", "add wiki", "add tasks"
+- "start project", "set everything up"
+- "let's start a project", "init"
+
+It also triggers when an agent is launched in a fresh folder that the user
+clearly intends to turn into a workspace.
+
+## Prerequisites
+
+`project-bootstrap` does not lay out `.wiki/` or `.tasks/` by itself — it
+delegates to two companion skills, which must be installed on the machine
+running it:
+
+- [`setup-wiki`](../setup-wiki/) — creates the canonical `.wiki/` layout.
+- [`setup-tasks`](../setup-tasks/) — creates the canonical `.tasks/` layout.
+
+If either is missing, `project-bootstrap` stops with a clear error rather
+than falling back to ad-hoc creation. This keeps layout drift between
+projects bootstrapped at different times debuggable.
+
+## What it creates
+
+| Path | Source | Notes |
+|---|---|---|
+| `.git/` | `git init` | Skipped if repo already initialized. |
+| `.gitignore` | `assets/.gitignore.template` | Skipped if file exists. |
+| `README.md` | minimal stub | Skipped if file exists. |
+| `.wiki/` | delegated to `setup-wiki` | Karpathy LLM Wiki layout — `CLAUDE.md`, `index.md`, `log.md`, `overview.md`, `raw/`, `entities/`, `concepts/`, `packages/`, `sources/`. |
+| `.tasks/` | delegated to `setup-tasks` | Canonical board — `STATUS.md` plus per-task `<task-slug>.md` files. |
+| `CLAUDE.md` | `assets/CLAUDE.md.template` | Skill triggers (`use superpowers`, `use project wiki`, etc.). On non-Windows hosts, swap the `we're on Windows` line for `we're on Linux` / `we're on macOS`. |
+| `.wiki/concepts/bootstrap-manifest.md` | generated | Records which skill versions initialized the project, so cross-project layout drift is debuggable. |
+
+## Workflow
+
+1. **Detect mode.** Inspect the current directory — git, `.wiki/`, `.tasks/`,
+   `CLAUDE.md`, `README.md` — and print a single summary block: what was
+   found, what will be created, what will be skipped.
+2. **Confirm.** One question, one confirmation. Nothing is written before the
+   user agrees.
+3. **Steps 1–5.** Create or skip each piece in order — git, README, `.wiki/`,
+   `.tasks/`, `CLAUDE.md`. Steps 3 and 4 delegate to the setup-skills.
+4. **Step 5.5.** Write `bootstrap-manifest.md` recording the versions of
+   `project-bootstrap`, `setup-wiki`, and `setup-tasks` used.
+5. **Commit.** `chore: bootstrap project structure` for fresh repos, or
+   `chore: upgrade project structure` adding only the new files for existing
+   ones. Pushes only on explicit user request.
+6. **Summary.** Final report — what was created, what was skipped, suggested
+   next step.
+
+## Rules
+
+- Never overwrite an existing file without explicit user confirmation.
+- Always show the plan before touching the filesystem.
+- Never invent project details — read what's already there.
+- Commit only files just created — never touch the rest of the tree.
+- Push only after the user explicitly says so.
+
+## Install
+
+From the repo root:
+
+**Windows (PowerShell):**
+
+```powershell
+bash scripts/install.sh project-bootstrap
+```
+
+**Linux / macOS (bash):**
+
+```bash
+bash scripts/install.sh project-bootstrap
+```
+
+`install.sh` works on Windows under git-bash. A native `install.ps1` is
+[planned](../../.tasks/STATUS.md) but not required.
+
+The skill installs to `~/.claude/skills/project-bootstrap/`. Override the
+target with `CLAUDE_SKILLS_DIR=/path bash scripts/install.sh …`.
