Conformance tests

Pull request overview

This PR introduces a live-API conformance test harness for the VRChat OpenAPI specification. Because VRChat publishes no official spec, the repo reverse-engineers it from real traffic; this PR adds the machinery to drive ~500 Arazzo workflows against the live API, capture the responses as HAR, and compare them against the bundled description to surface undocumented fields (drift) and untested routes (coverage). It also adds CLAUDE.md codifying the evidence-first documentation discipline and updates dependencies/scripts to support the new flow.

Changes:

• Adds test/run.sh (session-cache-aware suite runner with skip handling) and test/.env.example (credential template), plus a test/test:coverage/test:drift script set in package.json.
• Adds a vrchat/close-schemas Redocly decorator (redocly/plugin.ts) and an unpublished test bundle (redocly.yaml) that sets unevaluatedProperties: false on object schemas so drift can detect undocumented response fields.
• Updates .gitignore to exclude captures/credentials and refreshes dependencies (upgrades Redocly, drops unused packages, adds httpexec/totp-generator/typescript).

File	Description
test/run.sh	New suite runner: boots httpexec, manages session-cache login, applies default skips, writes the whole-suite capture.
test/.env.example	Credential template; two comments still use stale conformance naming (flagged).
redocly/plugin.ts	Adds close-schemas decorator closing object schemas via unevaluatedProperties, with an APIConfig opt-out.
redocly.yaml	Adds the unpublished test bundle that applies close-schemas for drift checking.
package.json	Reworks lint/test scripts, upgrades Redocly, adds test deps, removes unused ones.
CLAUDE.md	Documents the evidence-first workflow, tooling traps, and commands.
.gitignore	Ignores test/.out, .env* (except the example), and all *.har captures.
