docs: Remove WinGet from install instructions until registry submission

WinGet manifests are still generated by CI but DoiT.dci is not yet
registered in the WinGet registry. Drop WinGet references from
user-facing docs and clarify the status in Known Limitations.

Also add CLAUDE.md with project context for Claude Code sessions.

+# Claude Code Project Context
+
+## What Is This
+
+`dci` is the CLI for the DoiT Cloud Intelligence (DCI) API. It wraps [restish](https://github.com/rest-sh/restish) with DCI-specific configuration — auto-configured API base, OAuth2 via the DoiT Console, table-first output, and a locked-down command surface that exposes only DCI API operations. The entire CLI is a single `main.go` file. It ships as a Go binary distributed via Homebrew, Scoop, WinGet, and `.deb`/`.rpm` packages.
+
+## Commit Message Conventions
+
+GoReleaser changelog auto-generates from commits between tags. Filtered prefixes (excluded from changelog):
+- `docs:` — documentation-only changes (README, DISTRIBUTION.md, etc.)
+- `test:` — test-only changes
+- `chore:` — maintenance (manifest updates, CI config, dependency bumps)
+
+Commits without these prefixes appear in the GitHub Release changelog. Use prefixes deliberately.
+
+## Release Pipeline
+
+- GoReleaser v2 via `goreleaser-cross` Docker image
+- Tag `v*` triggers `release.yml` → `sync-manifests.yml` + `post-release-verify.yml`
+- Manifests (`Formula/dci.rb`, `bucket/dci.json`) are committed to main by CI
+- WinGet manifests generated but require manual PR to `microsoft/winget-pkgs`
+
+## Key Files
+
+- Single-file CLI: `main.go` (all logic) + `main_test.go`
+- Build config: `.goreleaser.yaml`
+- Release workflows: `.github/workflows/release.yml`, `sync-manifests.yml`, `post-release-verify.yml`
+- Package templates: `packaging/`
+
+## Project Conventions
+
+- README and DISTRIBUTION.md are user-facing — no internal jargon, no restish references
+- README targets end users; DISTRIBUTION.md targets developers/contributors
+- Homebrew tap works via GitHub redirect (`doitintl/homebrew-dci-cli` → `doitintl/dci-cli`)
+- Windows ARM64 excluded (upstream goreleaser-cross issue #117)

 ## Known Limitations
 
 - **Windows ARM64** is excluded due to a missing cross-compiler in `goreleaser-cross` ([goreleaser-cross#117](https://github.com/goreleaser/goreleaser-cross/issues/117)).
-- **WinGet** manifests are generated but not auto-submitted — they need manual PR submission to `microsoft/winget-pkgs`.
+- **WinGet** manifests are generated by CI as workflow artifacts (`packaging/winget/*.tmpl`), but `DoiT.dci` is not yet registered in the WinGet registry. To enable `winget install DoiT.dci`, the rendered manifests need to be submitted as a PR to [microsoft/winget-pkgs](https://github.com/microsoft/winget-pkgs). Until then, WinGet is omitted from install instructions.
 - **Homebrew tap** relies on a GitHub redirect from `doitintl/homebrew-dci-cli` to this repo. Do not create a repo named `homebrew-dci-cli` in the org.
