feat(install): add --local flag to install from local build

[ArtyETH06]

Summary

Adds a --local flag to both the CLI installer and the Electron GUI wizard so developers can test local changes without publishing to npm.

Usage

# Build first
pnpm --filter @leadbay/mcp build

# GUI wizard (same OAuth flow, installs node dist/bin.js instead of npx)
pnpm --filter @leadbay/mcp installer -- --local

# CLI (no GUI)
node packages/mcp/dist/bin.js install --oauth --local

# Explicit path
node packages/mcp/dist/bin.js install --oauth --local=/abs/path/to/dist/bin.js

What it does

Without --local, the wizard writes this into every client config:

{ "command": "npx", "args": ["-y", "@leadbay/mcp@latest"] }

With --local, it writes:

{ "command": "node", "args": ["/absolute/path/to/packages/mcp/dist/bin.js"] }

After each pnpm --filter @leadbay/mcp build, the next MCP session picks up changes automatically — no reinstall needed.

Changes

• install-claude-code.ts — buildClaudeCodeAddArgs accepts optional localBinPath
• install-json-config.ts — installInJsonConfig accepts optional localBinPath
• installer-gui.ts — reads --local from process.argv at startup, threads through installInto
• bin.ts — parses --local[=PATH] in runInstall, resolves absolute path, threads through

Base branch

Targets PR #69 (feat(mcp): add hosted HTTP server and installer wizard).
