Step 10 of the bounds rollout (ComlineProject/core#98, ComlineProject/core#197).

• Pins: the same revs as the CLI (Bounds on types, step 10: pins, migration, build --reconcile cli#130): comline-core 8f5dc91, generation c303722, comline-rust 2d50fbf, comline-typescript ea9b9e2. One copy of each in Cargo.lock. The comline.toml schema and checks come from comline-codegen's shared config types at that rev.
• Hover: core's grammar now has ArraySize::{Max, Exact}, so a type renders as written: char[max 32], u32[max 10], char[8], or a constant's name (char[max MAX_NAME]).
• Bounds syntax parses with core's grammar, so it gets no false errors. A schema whose strings and lists have no maximum gets core's bounds::unbounded errors, as comline build does.

Merge after ComlineProject/cli#130.

• validate_on_decode (round 2): the shared schema now types it as a mode (collect, the default, or first) or { off = "why" }. comline.toml checking follows a oneOf the same way it follows an anyOf, and completion offers collect and first. A bare "off" gets an error with a quick fix to { off = "why" }, as comline generate refuses it.

Merge after ComlineProject/generation#116, ComlineProject/comline-rust#104 and ComlineProject/comline-typescript#127, together with ComlineProject/cli#130.
