* PyBytes.title should be ASCII-only.
* Use icu_casemap over unicode-casing for titles
`icu_casemap` is consistently maintained, official, and tracks the
latest Unicode versions. RustPython is also using other `icu4x` crates,
so using `icu_casemap` is more consistent.
As with islower and isupper, tracking the latest Unicode version is
important because character definitions shift over time which causes
discrepancies between RustPython and CPython.
This commit fixes title().
* Use icu_casemap for capitalize()
I dropped unicode-casing because it's cleaner to use icu4x for
everything. `icu4x` will also stay up to date whereas unicode-casing
will need to be periodically updated with new Unicode tables. Dropping
unicode-casing also removes some binary bloat due to the tables.
`capitalize()` mimics CPython behavior more closely now as well.
Notably, I implemented CPython's sigma edge case handler.
* Match CPython's title() exactly
`sys.version_info` and `sys.implementation` are two different versioning
schemes. `version_info` refers to the target Python version while
`implementation` refers to the implementation version.
For RustPython, `version_info` should be 3.14 because it currently
targets Python 3.14. This was correct and remains unchanged.
`implementation`, however, should be set to RustPython's version. I
updated the code to correctly get RustPython's version from the
environment. I also ensured values are hard coded at build time which
reduces the overall code that needs to be run at runtime as well as
removes some unneeded allocations.

CPython convention: top-level module / interactive / expression code
does not carry CO_NEWLOCALS or CO_OPTIMIZED. The per-scope mapping at
enter_scope::CompilerScope::Module already returns empty flags, but
Compiler::new seeded the root CodeInfo with CodeFlags::NEWLOCALS,
forcing module code into the NEWLOCALS arm of frame.rs:725-731 so
locals were allocated as a fresh empty dict instead of being bound to
globals (the correct semantics for exec(code, globals)).
Restore the seed to empty() so it matches the per-scope mapping and
CPython's compiler_enter_scope for module scope.
* Align CFG cleanup bytecode with CPython
* Bytecode parity: fblock unwind, fstring join, folding, scope
- compile.rs: unwind_fblock_stack returns whether a finally ran so
return-statement emission can adjust location handling; restructure
try/except/finally cleanup to preserve or drop boundary NOPs based on
whether the body falls through; rework f-string lowering with
count/join helpers; remove the per-collection-type heuristic for
AST-level folding and defer to flowgraph passes; add several folding
helpers and a ComprehensionLoopControl enum.
- ir.rs: re-run unary/binop folding around tuple folding, add
reorder_conditional_scope_exit_and_jump_back_blocks and several block
classification helpers, add MAX_STR_SIZE, change is_exit_without_lineno
to take the block list.
- symboltable.rs: in analyze_cells, remove names owned as cells in
function-like scopes from the parent's free set; mark lambda scope
type explicitly.
* Refine CFG scope-exit backedge ordering
