v1.0

First stable release. The acceptance gate defined in the README — zero
ERROR/MISSING on the acceptance corpus — is met across a corpus that
grew ~8x in coverage during the v0.9 → v1.0 cycle.

Grammar features closed (20)

raises, var, comptime (expression + statement-prefix), alias,
trait, typed raises ErrorType, ref [origin] T return-type syntax,
var / mut / read / owned conventions on *name variadic
parameters, // infer-only marker and keyword arguments in [...]
parameter lists, decorators on struct / trait, Self, ^ ownership
transfer, argument conventions before variadic *name, comptime_statement
prefix on if / for / while / assert, and the rest of the
follow-up gaps from PRs #41–#44.

Corpus widening

	v0.9	v1.0
Files	4	31
Lines (approx.)	~640	~12,000
Source projects	1 (fusemojo)	6 (fusemojo, modular/modular stdlib, lightbug_http, MAX, mojojson, decimo)

Verification

tree-sitter test          -> 78/78
script/check-errors.sh    -> 0 ERROR/MISSING across 31 files
CI                        -> green
