Add Quick Prompts plugin (noobitoo.quick-prompts)

[NooBiToo]

Adds a community productivity plugin to the marketplace index.

Plugin

• id: noobitoo.quick-prompts
• source: https://github.com/NooBiToo/orca-quick-prompts.git @ v0.1.0
• categories: ["productivity"] (community; no official)
• requires: Orca >=1.4.0, pluginApi 1

What it does

One-click prompt snippets for agent terminals — instead of digging through
settings, copying a command, and pasting it into the chat:

• Side panel (workspace:read + terminal:send): terminal picker for the
  focused worktree plus built-in prompt buttons (RU + EN): code review,
  write tests, security check, explain commit, task plan, refactor,
  commit message, continue. Text is typed into the selected terminal
  without Enter unless the user opts in.
• Palette commands: insert the most popular prompts into the focused
  worktree's terminal; open the personal prompt library.
• Personal prompt library: the worker hosts a localhost page (binds
  127.0.0.1) for CRUD over custom prompts with one-click insertion into the
  focused worktree's terminal. Prompts live in the user profile
  (~/.orca-plugin-config/orca-quick-prompts.json) — outside the immutable
  install tree, so user edits never trip the host's content-hash integrity
  check.

Capabilities requested: workspace:read, terminal:send, storage,
settings:own — no network access at all.

Validation

• Install from git URL with #ref verified end-to-end on Orca 1.4.192
  (Windows): install → review → enable → panel in the right sidebar →
  insert into agent terminal.
• 20 local assertions (node scripts/test-local.mjs): prompt normalization,
  user-profile storage, terminal resolution, library server CRUD and
  insert-through-host.

Note

Third plugin from the same author as #3 (Russian language pack) and #4
(Telegram notifications); all three PRs are independent.
