Reorganize parallel programming lectures and improve content flow (#429)

* Reorganize parallel programming lectures and improve content flow

Major restructuring of parallelization-related content across lectures to
improve pedagogical flow and consolidate related material.

* Complete JAX intro lecture: add pure functions content and fix errors

- Add comprehensive "Random numbers and pure functions" section
- Demonstrate NumPy's impure random number generation vs JAX's pure approach
- Fix spelling errors: discusson→discussion, explict→explicit, parallelizaton→parallelization, hardward→hardware, sleve→sleeve, targetting→targeting
- Fix grammar: "uses use"→"uses", "short that"→"shorter than", "function will"→"functions will", "Prevents"→"Prevent"
- Fix missing jax. prefix in random number examples
- Improve clarity and consistency throughout

* Reorganize JAX intro lecture for improved pedagogical flow

Major restructuring:
- Move Functional Programming section earlier (after NumPy Replacement)
- Integrate pure functions discussion into Random Numbers section
- Move "Compiling non-pure functions" into JIT section
- Add smooth transitions between sections

This creates a logical progression: basics → philosophy → features
Readers now understand WHY before seeing HOW, making JAX's design
choices (like explicit random state) more intuitive.

Also fix syntax errors in timer code blocks (missing colons).

- Remove "Speed Comparisons" section (moved to numpy_vs_numba_vs_jax.md)
- Remove "Implicit Multithreading in NumPy" section (moved to numpy_vs_numba_vs_jax.md)

**numpy_vs_numba_vs_jax.md:**
- Change title from "Parallelization" to "NumPy vs Numba vs JAX"
- Add jax to pip install command
- Add missing imports: random, mpl_toolkits.mplot3d, matplotlib.cm

* Fix grammar and reorganize need_for_speed.md content

- Fix incomplete sentence: add missing word "compiler" (line 229)
- Fix header level inconsistency: change Multi-GPU Servers to #####
- Reorganize Overview section with clearer structure
- Simplify Python's Scientific Ecosystem section
- Restructure "Pure Python is slow" section for better flow
- Add concrete vectorization speed comparison example

* Fix missing random module import in need_for_speed.md

Add missing `import random` statement to fix NameError when running
the vectorization example code that uses random.uniform().

Tested by converting to Python with jupytext and running successfully.

* Fix header hierarchy inconsistencies in need_for_speed.md

Changed level 5 headers (#####) to level 4 headers (####) to fix
invalid header hierarchy that was causing build failures.

Fixed headers:
- "GPUs and TPUs"
- "Why TPUs/GPUs Matter"
- "Single GPU Systems"
- "Multi-GPU Servers"

These were incorrectly using ##### (level 5) directly under ### (level 3)
headers, skipping level 4. Now properly using #### headers.

* Complete numpy_vs_numba_vs_jax lecture with timing comparisons

Added comprehensive comparisons between NumPy, Numba, and JAX for both
vectorized and sequential operations:

- Added Numba simple loop and parallel versions for vectorized example
- Demonstrated nested prange parallelization and its limitations
- Added detailed discussion of parallelization overhead and contention issues
- Implemented sequential operation (quadratic map) in both Numba and JAX
- Used JAX lax.scan with @partial(jax.jit, static_argnums) for cleaner code
- Added timing code with separate runs to show compile vs cached performance
- Included educational discussion without specific numbers (machine-independent)
- Added explanation of reduction problem challenges with shared variable updates
- Fixed spelling error: "implict" → "implicit"
- Added missing punctuation

All code examples tested and verified to run successfully.
