fix(exceptions): restore backwards compatibility for instructor.excep…

…tions imports (#1789)

## Summary
- Restore backwards compatibility for `instructor.exceptions` imports
that broke in v1.11.0
- Add deprecation warnings to guide users to new import path
`instructor.core`
- Bump version to 1.11.2 (patch version for backwards compatibility fix)

## Problem
Version 1.11.0 introduced a breaking change by removing the backwards
compatibility module `instructor/exceptions.py`. This caused imports
like `from instructor.exceptions import InstructorRetryException` to
fail, breaking downstream applications without warning.

## Solution
- Recreated `instructor/exceptions.py` with proper re-exports from
`instructor.core.exceptions`
- Added deprecation warnings to guide users to the recommended import
path
- Used proper semantic versioning (patch bump) for a backwards
compatibility fix

## Test plan
- [x] Test that old import path works: `from instructor.exceptions
import InstructorRetryException`
- [x] Test that new import path still works: `from instructor.core
import InstructorRetryException`
- [x] Verify deprecation warning is shown when using old import path
- [x] Run linting and type checking
- [x] Version bump to 1.11.2
