fx 0.7.4 - composition under regions

fx 0.7.4 — composition under regions

Language package for ledocorp/fxlang
Docs: ledocorp.org/fx · composition · tracking

Composition-under-regions pack closeout. Tag: v0.7.4.

Highlights

Area	What landed
Composition method	docs/COMPOSITION.md — ids/pools, local mut, grow/freeze discipline
Dual-emit tracking	docs/TRACKING.md — annotate / .fxmap / #line / fx locate
Pool / ids	std/pool + lib/id_pool (make/alloc/get/set/len)
Slot mut	vec_set(v, i, x) (needs mut) — stable slot write; still no v[i]=x
Patterns	examples/pattern_{ids,mut_table,grow_freeze,ring,pool}
Native emit	vec_set in live sh_* CallExpr (FX-SH-NAT-8)
Honesty	No unsafe dialect; phase types / convenience helper skipped

Install

fx doctor
fx version                 # expect v0.7.4
fx new hello && cd hello && fx run main.fx   # exit 42

Try

fx run examples/pattern_pool/main.fx
fx run examples/pattern_ids/main.fx
fx run examples/tool_result/main.fx

Honesty bounds

Still out: full generic Map<K,V>, &mut Vec as slice, mut sub-slices, Vec index assign sugar, traits/closures/Option, package manager, advanced fx Runtime, Neuton. No unsafe path.
