v1.5.1: chore: 1.5.1 - add mcpName + server.json for official MCP Registry

Publishes io.github.PramodDutta/browserbash to the official MCP
Registry (registry.modelcontextprotocol.io). mcpName in package.json
is the ownership proof the registry validates against the npm package;
server.json is the registry manifest. No runtime change.

v1.5.0 — the validation-layer release

BrowserBash becomes directly consumable by AI agents, and verdicts stop being model judgment.

Highlights

• MCP server: browserbash mcp — plug into Claude Code, Cursor, Codex or any MCP host with one line: claude mcp add browserbash -- browserbash mcp. Tools: run_objective, run_test_file, run_suite.
• Deterministic assertions: Verify ... steps compile to real Playwright checks (no LLM judgment); run_end.assertions carries expected-vs-actual evidence.
• testmd v2: version: 2 frontmatter — per-step execution on one browser session, plus deterministic API steps for arrange-act-assert suites.
• Saved logins: browserbash auth save <name> + --auth — log in once, reuse everywhere.
• Monitor mode: browserbash monitor --every 10m --notify <webhook> — alerts only on pass/fail changes; Slack autodetected.
• Cost governance: cost_usd estimates, suite --budget-usd hard stop.
• Sharding + viewport matrix: --shard 2/4, --matrix-viewport.
• Playwright import: browserbash import ./e2e with an honest IMPORT-REPORT.md.
• Flow recorder: browserbash record <url> — passwords never captured.
• GitHub Action: action.yml at repo root; PR verdict comments; see docs/github-action.md.
