docs: switch mcp-bridge invocation from node to deno run -A

[hyperpolymath]

Summary

mcp-bridge/main.js is a Deno program (uses Deno.env.get, Deno.stdin.readable, Deno.exit — confirmed via grep; ships mcp-bridge/deno.json with Deno task config). Several user-facing docs and package.json's "start" script told users to launch it with node, producing ReferenceError: Deno is not defined on first install.

This came from a 2026-04-30 install session where the maintainer hit that exact error running claude mcp add ... -- node ... mcp-bridge/main.js per the README.

Premise verification: grep -n 'Deno\.' mcp-bridge/main.js returns lines 249, 496, 507 — confirmed Deno API usage. mcp-bridge/deno.json exists with deno run --allow-net --allow-env --allow-read main.js as its start task.

Files changed

File	Lines changed	Rationale
package.json	1	scripts.start used node mcp-bridge/main.js; changed to deno run -A mcp-bridge/main.js so npm start works
README.md	1	Clone-and-configure snippet instructed claude mcp add boj-server -- node mcp-bridge/main.js
README.adoc	2	Two install snippets: one with absolute path (node /path/to/…), one relative (node mcp-bridge/main.js)
docs/index.html	1	Landing-page install snippet had node /path/to/boj-server/mcp-bridge/main.js

Total: 4 files, 5 lines changed (5 substitutions).

Deliberately left alone

Item	Reason
mcp-bridge/main.js	Source is already correct Deno — no change needed
package.json → bin.boj-server	npx/npm-publish story for a Deno bridge needs its own decision; out of scope for this PR
package.json → scripts.test (node --test …)	Runs the Node test runner against dispatch_test.js; separate from bridge invocation
README.adoc line 107 (node --test mcp-bridge/tests/)	Same — test-runner invocation, not bridge launch
package.json → engines.node	One-line cleanup per request scope; engines block left as-is
docs/practice/DOGFOOD-LOG.adoc line 149	Historical incident log recording a past /usr/bin/node bug; editing a log entry would falsify the record
All workflow / cartridge / service files	Explicitly out of scope

How to test

git clone https://github.com/hyperpolymath/boj-server
cd boj-server/mcp-bridge
# Start the BoJ REST API first (port 7700), then:
claude mcp add boj-server -- deno run -A mcp-bridge/main.js

No more ReferenceError: Deno is not defined.
