Summary

Enable Ruby LSP on-type formatting by default by removing the extension's onTypeFormatting: false workaround for #38. Ruby LSP enables the feature by default; user-supplied initialization options, including an explicit opt-out, pass through unchanged.

Release prerequisites

Keep this PR in draft until both fixes have shipped:

• A Zed release includes Fix on-type formatting using a stale position when autoindent is pending zed-industries/zed#65769 (on-type formatting request positions and cursor placement after autoindent).
• A Ruby LSP gem release includes skip comment continuation when the editor already inserted the prefix Shopify/ruby-lsp#4242 (avoid duplicate comment prefixes when the editor continues comments).
• Record the released Zed and Ruby LSP versions here and verify the behavior below with those versions before merging.

Projects using a bundled or otherwise pinned Ruby LSP must update to a gem release containing the fix.

Validation

• cargo test --locked --offline — 79 tests passed.
• cargo check --locked --offline --target wasm32-wasip2 — passed.
• cargo fmt --check and git diff --check — passed.

Manual verification with released fixes is pending:

• With no on-type formatting override, pressing Enter after def foo or do |x| inserts an indented body and closing end, keeping the cursor in the body.
• Heredoc terminators, block parameter pipes, and string interpolation complete with correct cursor placement.
• Pressing Enter after # hello continues the comment with one # prefix.
• An explicit lsp.ruby-lsp.initialization_options.enabledFeatures.onTypeFormatting: false still disables the feature.
