Add CHANGELOG.md

Notable changes since v1.1.1:
- New -e/--edit flag opens the active config file in $EDITOR.
- Lazy import of keeper.ts so --help and --version skip the nut.js
  native load on cold start.
- Various audit cleanups: failRuntime() mirror, named Logger interface,
  errors.ts module, autoDelayMs moved out of module-load side effects,
  defaultConfigPath guards against unset HOME, noUncheckedIndexedAccess
  enabled in tsconfig.
- Added Bun test suite (34 tests across resolveConfig, loadConfigFile,
  editConfig).
- scripts/dev-setup.sh made POSIX-portable.

+# Changelog
+
+All notable changes to `move` are documented here.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [1.2.0] - 2026-06-17
+
+### Added
+- `-e, --edit` flag opens the resolved config file in `$EDITOR`.
+
+### Changed
+- `keeper.ts` (and `@nut-tree-fork/nut-js`) is lazy-imported, so `--help`
+  and `--version` skip the nut.js load and start ~10x faster.
+
+## [1.1.1] - 2026-06-17
+
+### Changed
+- Tests moved from `src/` to a top-level `tests/` directory.
+- `tsconfig.json` sets `"types": ["bun"]` so VS Code resolves `bun:test`.
+
+### Fixed
+- `package.json` version now matches the published tag.
+
+## [1.1.0] - 2026-06-17
+
+### Added
+- JSON config file support at `${XDG_CONFIG_HOME:-~/.config}/move/config.json`.
+  Precedence: CLI flags > config file > defaults. Strict validation.
+- `-C, --config <path>` to override the default config path.
+- Installer seeds `config.json` with project defaults on fresh install only.
+- Bun test suite for `resolveConfig` and `loadConfigFile`.
+
+### Changed
+- Installer scripts now live in `scripts/`.
+- `verbose` is now a first-class `Config` field; `resolveVerbose` removed.
+- `CliError` extracted into `src/errors.ts`.
+- `defaultConfigPath()` throws when both `$XDG_CONFIG_HOME` and `$HOME` are unset.
+- `mouse.config.autoDelayMs = 0` moved into `runKeeper` (no module-load side effect).
+- Runtime errors go through a `failRuntime` helper that mirrors `failUser`.
+- `keeper.ts` declares a named `Logger` interface.
+- `dev-setup.sh` is now POSIX `sh`.
+- `tsconfig.json`: enabled `noUncheckedIndexedAccess` and `resolveJsonModule`.
+
+## [1.0.1] - 2026-06-17
+
+### Added
+- End-user `install.sh` runnable via `curl ... | sh`. XDG-respecting, idempotent.
+- `uninstall.sh` removes the wrapper and install tree; leaves Bun and user
+  config alone.
+- `dev-setup.sh` for contributors.
+
+### Removed
+- `DISTRIBUTION-PLAN.md` (design notes, superseded by the implementation).
+
+## [1.0.0] - 2026-06-15
+
+Initial release.
+
+### Added
+- `move` CLI for keeping presence-tracking apps marked Available by nudging
+  the cursor after a configurable idle period.
+- Flags: `-h/--help`, `-v/--version`, `-m/--move-interval`,
+  `-c/--check-interval`, `-d/--step-delay`, `-n/--step-count`, `-V/--verbose`.
+- Quiet-by-default logging.
+- Source split into `src/{move,cli,config,keeper}.ts`.
+- `bin` entry + shebang so `bun link` registers `move` globally.
