f7352b51b0 rename: uncommonlisp -> lumbda throughout the repo 
Historical internal name "uncommonlisp" retired in favor of the
public name "lumbda" ahead of lumbda.com going live. Scope of
this commit:

Source files renamed:
  uncommonlisp.py                     -> lumbda.py
  asm/uncommonlisp.s                  -> asm/lumbda.s
  c/uncommonlisp.h                    -> c/lumbda.h
  whitepaper/uncommonlisp-whitepaper  -> whitepaper/lumbda-whitepaper (.rst + .pdf)

Binaries renamed (tracked ones; c/ was always gitignored):
  asm/uncommonlisp, asm/uncommonlisp-gc, asm/uncommonlisp.o,
  asm/uncommonlisp-gc.o                -> asm/lumbda(-gc)(.o)
  c/.gitignore                          -> ignores lumbda

Internal string updates (sed pass ordered longest-first):
  asm/uncommonlisp -> asm/lumbda
  c/uncommonlisp   -> c/lumbda
  uncommonlisp.py  -> lumbda.py
  UNCOMMONLISP_BIN -> LUMBDA_BIN (asm/test.sh env var)
  "uncommonlisp> " -> "lumbda> " (asm REPL prompt baked into binary)
  UNCOMMONLISP     -> LUMBDA (macros, comments)
  uncommonlisp     -> lumbda (prose)

Binary portal magic updated:
  "ULPORTAL" -> "LUMBDAB1"   # "Lumbda Binary v1"
Old portal files are not backward-compatible — this is a deliberate
break since it's the rename moment. S-expression portals already
carry their own ";; lumbda-portal v1" header and remain cleanly
versioned.

WHITEPAPER.pdf / WHITEPAPER.rst symlinks repointed to the renamed
files. Makefile's whitepaper target targets lumbda-whitepaper.pdf.

Not changed (intentional, separate phases):
  - Filesystem directory /home/fox/git/uncommonlisp itself
    (fox renames locally and the gitlab repo URL in a follow-up)
  - tests.py hardcoded cwd=/home/fox/git/uncommonlisp
    (matches the current on-disk location; will flip when the
    directory rename ships)
  - Git history (immutable; old commits still say uncommonlisp,
    which is correct — that's what they were)

Verified:
  137 asm no-GC + 137 asm GC + 571 Python + 83 C + 189 shared
  functional tests all pass under the new names.
  bench-gc-http (2000 req): all 4 cells behave as expected
  (cells 1/2 flat, 3 leaks, 4 bounded at 1 chunk).
  Python REPL, C REPL, asm REPL all start cleanly.

52d14a2f59 Add parameterize fix, let-values, case=>, arithmetic, FS/system builtins, tracing, SRFI-64 
Correctness:
- Fix parameterize: was restoring current value instead of saved old value
- Add let-values and let*-values special forms (R7RS multi-value binding)
- Update case macro to handle (datum... => proc) clauses

Numeric tower:
- truncate-quotient, truncate-remainder, floor-quotient, floor-remainder
- square, exact-integer?

Vectors:
- vector-copy now accepts optional start/end bounds
- vector-copy! for destination-vector mutation

File system and system interface:
- file-exists?, delete-file, rename-file, current-directory,
  set-current-directory!, directory-files, make-directory,
  file-size, file-directory?, file-regular?
- command-line, get-environment-variable, current-time,
  current-jiffy, jiffies-per-second, flush-output-port

Debuggability:
- Call stack tracing: _call_stack captured in LispErr.call_stack
  _call() pushes/pops frames; REPL prints last 5 frames on error
- trace/untrace macros + make-traced/untrace-proc builtins
  (set! f (make-traced f 'f)) wraps f to print args and return values

stdlib.lsp:
- SRFI-64 lightweight test framework: test-begin, test-end,
  test-assert, test-equal, test-error macros

Tests: 455 → 491 (+36 new tests)

f72190d2dc Initial implementation of uncommonlisp 
Single-file Scheme-like Lisp interpreter in Python with:
- TCO via explicit while loop (no Python stack overflow at any depth)
- syntax-rules with ellipsis for hygienic macros
- define-macro for procedural macros
- Full numeric tower, strings, chars, vectors, hash tables
- SRFI-1 list library
- call/cc (escape continuations), values, dynamic-wind, guard
- Python interop (py-eval, py-import, py-call, py-attr)
- 396 passing unit/integration/functional tests
- stdlib.lsp with 60+ utility functions
- Benchmark suite vs CPython baseline
