Replace hardcoded LZMA thread count with LZMA_THREADS(ctx)
...
The LZMA encoder was called with numThreads=8 at all 19 call sites,
but LZMA only supports 1 or 2 (and _7ZIP_ST forces it to 1 anyway).
Replace with LZMA_THREADS(ctx) macro that clamps ctx->num_threads
to [1, 2], making the code say what it means and honoring the
consumer's threading preference from the threads=N option.

Add multi-threaded zstd compression support
...
Switch zstd encoder from simple API (ZSTD_compress) to advanced API
(ZSTD_CCtx + ZSTD_compress2) with configurable worker threads via
ZSTD_c_nbWorkers. Consumer controls threading through threads=N
option string parameter. Default is 1 (single-threaded, bit-identical
output to previous behavior).
- Enable ZSTD_MULTITHREAD compile definition and link pthreads
- Add num_threads field to options struct and context
- Parse threads=N in option string (clamped >= 1)
- Rewrite aaruf_zstd_encode_buffer() with num_threads parameter
- Update all call sites (write.c, close.c)

spec: fix block alignment shift formulas in DDT2 spec
...
The spec used `2 << x` where `1 << x` (= 2^x) was intended.
`2 << x` equals 2^(x+1), which is off by factor 2. The code
unanimously uses `1 << x` across 40+ sites. Corrects the
example result from 0x6A0000 to 0x350000 accordingly.

lru: use native uint64 keys instead of string conversion
...
Replace string-keyed uthash lookups with HASH_FIND/HASH_ADD on native
uint64_t keys. This eliminates per-lookup malloc/snprintf/strlen/free
overhead from the block cache hot path (2 lookups per sector read).
Before: malloc(17) + snprintf hex + HASH_FIND_STR + free per lookup
After: HASH_FIND with 8-byte integer key, zero allocations
Also removes the unused string-key API (find_in_cache/add_to_cache)
and the uint64_to_string helper — all callers use uint64 keys.
Fix off-by-one in eviction: >= caused cache to hold max_items-1
entries instead of max_items. Changed to > so the configured
capacity is honored exactly.
