Implements FTS5-style INSERT INTO v(v) VALUES ('optimize') command that
packs live entries from newer/sparser chunks into free slots of older
chunks, then deletes emptied chunks. Adds hidden command column to vtab
schema, command dispatcher in xUpdate, and two-pointer compaction
algorithm that handles vectors, all metadata types, and partitioned tables.
Includes 16 Python tests, 7 C unit tests, and a libFuzzer target.

Add test-only wrappers behind SQLITE_VEC_TEST compile flag to expose
static distance functions for unit testing. Includes tests for
distance_l2_sqr_float (4 cases), distance_cosine_float (3 cases),
and distance_hamming (4 cases). Print active SIMD flags at test start.

Add SQLITE_EMPTY tests for non-vector column inputs (primary key,
partition key, unknown types) and SQLITE_ERROR tests for zero
dimensions and empty brackets. Tighten existing error assertions
from rc != SQLITE_OK to exact expected return codes.

- Expand sqlite-vec-internal.h with scanner/tokenizer types, vector column
definition types, and parser function declarations
- Fix min_idx declaration to match actual C signature (add candidates,
bTaken, k_used params)
- Compile test-unit with -DSQLITE_CORE and link vendor/sqlite3.c so
sqlite3 API functions (sqlite3_strnicmp, sqlite3_mprintf, etc.) resolve
- Add unit tests for vec0_token_next, Vec0Scanner, and
vec0_parse_vector_column
- Fix Rust build.rs to define SQLITE_CORE and compile vendor/sqlite3.c
- Fix Rust min_idx FFI signature and wrapper to match actual C function
