chore: install 37 tessl doc tiles and add weekly update workflow

Vendor documentation tiles for project dependencies:
- Python (27): pytest, gitpython, libcst, jedi, tree-sitter, tomlkit,
  attrs, requests, pydantic, humanize, posthog, click, inquirer,
  sentry-sdk, parameterized, dill, rich, lxml, crosshair-tool,
  coverage, platformdirs, pygls, filelock, memray, mypy, uv, pytest-cov
- JS/TS (6): jest, vitest, mocha, typescript, better-sqlite3, @babel/core
- Java (4): gson, jacoco-agent, junit-jupiter, @babel/preset-typescript

Add scheduled GitHub Action (weekly Monday 9am UTC) that updates
existing tiles, attempts to install 21 missing tiles, and auto-prunes
the list as they become available.
