chore: drop Meta licensing (hook + headers) (#342)

## Summary
This is no longer a project requiring a meta license. Two-commit
cleanup:

1. **Drop the pre-commit hook + header file** so new files don't get
re-stamped:
   - Remove the \`insert-license\` hook from \`.pre-commit-config.yaml\`
- Delete \`scripts/license_header.txt\` (the Meta-attribution header it
injected)
2. **Strip existing headers** from every \`.py\` / \`.sh\` in the tree
(286 files) — removes the 5-line \`Copyright (c) Meta Platforms, Inc.
and affiliates\` block.

## Test plan
- [x] No \`Meta Platforms\` references remain anywhere in the tree
- [x] \`.pre-commit-config.yaml\` parses; remaining hooks (ruff,
ruff-format, blacken-docs, etc.) are untouched
- [ ] CI: pre-commit job is green and no longer runs \`insert-license\`
