* feat(typing): Reuse `Literal`(s) in `channels` overloads

* build: run `generate-schema-wrapper`

* feat(typing): Generate `Literal`(s) using `"const"`

Previously only `"enum"` was considered, meaning `"const"` was represented as `str` - rather than a **single** valid `str` value.

* build: run `generate-schema-wrapper`

* fix(typing): Update `Chart` annotations to match now narrower schema

* fix: Ensure rewrapped `Literal`(s) order is deterministic

* chore: Dummy to retrigger action

* refactor: Fix `C901` complexity in `SchemaBase.copy`

The nested functions do not reference `self` and can be split out, much like `.to_dict` -> `_todict`.
Saw this as a chance to add annotations as well. I think this helps illustrate that `.copy` is a noop for anything other than `SchemaBase | dict | list` - which I think might need to be addressed in the future.

* refactor: Further simplify `SchemaBase.copy`

10 lines shorter and is no longer constrained to `list` on the assert.
May be slightly faster on `python<3.11` which do not have zero-cost exceptions https://docs.python.org/3.11/whatsnew/3.11.html#misc

* refactor(perf): Merge identical `_shallow_copy` branches

Remembered a related `ruff` rule [FURB145](https://docs.astral.sh/ruff/rules/slice-copy/).
Wouldn't have made this fix, but likely would have led someone there

* refactor(perf): Reduce `_deep_copy`

- Initialize an empty set **once** at origin, rather than creating a new list per iteration
  - Renamed to `by_ref` in the new private function, to better describe the operation.
  - No change to public API.
- Define a partial `copy` to reduce repetition
- Use a genexpr for `args`, to avoid unpacking twice

* chore(typing): Add `pyright` ignores in `schemapi.py`

* fix(typing): Address most issues in `_FromDict.from_dict`

This method is far too dynamic to fix everything.
Removed the need for one `mypy` specific ignore as well.

* chore(typing): Ignore caught AttributeError

* chore(typing): Add ignore in `validate_jsonschema`

* fix(typing): Resolve `pyright` & `mypy` errors in `validate_jsonschema`

* build: run `generate-schema-wrapper`

…hide_fourth` (#3546)

Working on a different branch I had to track down the comment explaining that this should display only 3 errors.
The original name lead me to expect 4 errors
