feat(core): migrate ReScript to AffineScript with 66-test suite

[hyperpolymath]

Summary

• Migrates all source modules from ReScript (.res) to AffineScript (.affine)
• Adds tests/ directory with 66 passing tests covering ByteDetector, PathHandler, SafeWhitespace, and TextTransform
• Adds scripts/build-all.sh for reproducible builds (deno task shell lacks POSIX for-loop)

Technical notes

Compiler workaround (issue #122): AffineScript alpha does not inline zero-arg enum variant constructors or non-imported transitive dependencies across module boundaries. scripts/build-all.sh post-patches TextTransform.deno.js after compilation to inject the three missing symbols (LF/CRLF/CR, is_invisible, concat). Tracked in upstream AffineScript issue #122.

Transform ordering fix: moved normalize_line_endings to run after trim_lines_fn; the previous ordering caused JS .trim() to strip \r from CRLF line endings (splitting on \n leaves a trailing \r per line which .trim() removes, discarding the normalization result).

Test plan

• deno task build-all compiles all .affine → .deno.js and injects workaround
• deno test --allow-read --allow-write tests/ → 66 passed, 0 failed
• deno task build-all && deno task test — end-to-end pipeline clean
