Reorganize anchor/ examples into standalone projects

- Convert monorepo to 5 independent Anchor projects
- Each operation (create, update, close, reinit, burn) is now standalone
- Add setup helpers in each test file
- Replace sleep() with confirmTransactionIndexed() for reliable test synchronization
- Add comprehensive README with technical descriptions
- Update counter example with confirmTransactionIndexed()

Each project contains:
- Complete workspace configuration
- Program with single operation instruction
- Rust tests in programs/{name}/tests/test.rs
- TypeScript tests in tests/{name}.ts
- Independent build and test capability

 # Basic Operations - Anchor Programs
 
-Programs built with the Anchor framework with basic compressed account operations.
+Standalone Anchor programs for compressed accounts.
 
-## Programs
+## Structure
 
-- **create** - Initialize a new compressed account
-- **update** - Modify data in an existing compressed account
-- **close** - Close a compressed account and reclaim rent
-- **reinit** - Reinitialize a previously closed compressed account
-- **burn** - Permanently destroy a compressed account (cannot be reinitialized)
+Each operation is an independent Anchor project:
+
+- **create** - Initialize a new compressed account with `new_init()`
+- **update** - Modify data in an existing compressed account with `new_mut()`
+- **close** - Clear account data while preserving address with `new_close()`
+- **reinit** - Reinitialize a closed account with `new_empty()`
+- **burn** - Permanently delete a compressed account with `new_burn()`
+
+Each project contains its own workspace, program, and tests.
