Script mode with shebang support

Description:

Add script mode to seqc so .seq files can be run directly with shebangs:

#!/usr/bin/env seqc
: main ( -- Int ) "Hello from script!" io.write-line 0 ;

chmod +x hello.seq
./hello.seq

Proposed behavior:

Detect script mode when first argument is a .seq file
Compile with -O0 (fast compile, no optimization)
Cache compiled binary in $XDG_CACHE_HOME/seq/ (keyed by source hash + include hashes)
Run cached binary if cache hit, otherwise compile → cache → run
Pass remaining argv to the script

Cache details:

Key: hash of source content + hashes of all includes
Location: $XDG_CACHE_HOME/seq/ or ~/.cache/seq/ fallback
No cleanup policy initially (user can rm -rf the cache)

Non-goals (for now):

Optimized builds (use seqc build for that)
Incremental compilation
Automatic cache eviction
