Cut 0.2.11 with review receipts

[onatozmenn]

What this changes

Cuts 0.2.11 so deed review, its three policy gates, and the MCP deed_review tool are installable. The browser artifact now exposes the same receipt over a before/after source pair, and a new how-to carries a copy-paste pull-request workflow.

Why this way

The review receipt is computed once in deed-driver; MCP and wasm only adapt their inputs. The CI example compares detached base/head worktrees so generated or untracked files cannot enter the evidence, and pins both installer and binary to v0.2.11.

What it still does not do

The wasm export compares one module per side; CLI and MCP remain the module-set surfaces. The website pin and crates.io publication follow the merged tag rather than claiming an artifact that does not exist yet.

Checks

• cargo fmt --check
• cargo clippy --workspace --all-targets -- -D warnings
• 2521/2521 nextest tests and 12 doctests
• deed check examples (0 errors, 3 intentional warnings)
• deed test examples (138 passed)
• cargo publish --workspace --dry-run --locked (20 packages)
• wasm artifact smoke in Node, including the review receipt
• extracted workflow passes actionlint and a clean worktree comparison

Pull request overview

This PR prepares the 0.2.11 release by updating workspace versions, adding a CI how-to for reviewing PR patches via deed review, and unifying the “review receipt” output across CLI/MCP/wasm surfaces (including a new wasm export).

Changes:

• Bump workspace/crate versions to 0.2.11 and update release-facing docs (README + CHANGELOG).
• Add a GitHub Actions CI workflow guide that reviews PRs using detached base/head worktrees.
• Export deed_review from the wasm artifact and route MCP deed_review through deed-driver::review::review_sources to share one receipt implementation.
