Extract sigil-json from sigil monorepo

Message

- Filter-repo'd history preserving original SHAs from packages/sigil-json/. - Rewrote package.sgl: version 0.13.1, standalone url, resolve sigil-stdlib via from-git against sigil monorepo v0.13.1. - Added .gitignore (build/, .sigil/), manifest.scm (guix dev env), dev-redirects.sgl (point sigil-stdlib at local ../sigil checkout), README.md.

Extraction per procedures/sigil-package-extraction. No behavior changes.

# sigil-json
+2
+3
JSON parsing and generation for [Sigil](https://codeberg.org/sigil/sigil).
+4
+5
Bidirectional conversion between JSON and native Scheme types (dicts,
+6
arrays, strings, numbers, booleans) with port-based I/O for reading and
+7
writing JSON streams.
+8
+9
This package was extracted from the sigil monorepo — the in-tree history
+10
under `packages/sigil-json/` is preserved here as `master`.
+11
+12
## Usage
+13
+14
```scheme
+15
(import (sigil json))
+16
+17
;; Encode
+18
(json-encode #{ name: "Alice" age: 30 })
+19
; => "{\"name\":\"Alice\",\"age\":30}"
+20
+21
;; Decode
+22
(json-decode "{\"name\":\"Alice\",\"age\":30}")
+23
; => #{ name: "Alice" age: 30 }
+24
+25
;; Path lookup
+26
(json-get-in (json-decode "{\"a\":{\"b\":42}}") '(a b))
+27
; => 42
+28
```
+29
+30
## Type Mapping
+31
+32
| JSON | Scheme |
+33
|--------|----------------------------|
+34
| object | dict: `#{ name: "Alice" }` |
+35
| array | array: `#[1 2 3]` |
+36
| string | string: `"hello"` |
+37
| number | number: `42`, `3.14` |
+38
| true | `#t` |
+39
| false | `#f` |
+40
| null | `'null` symbol |
+41
+42
JSON `null` decodes as the symbol `'null` (not `#f`). When a field may be
+43
JSON null, normalize it explicitly — see `docs/json.md` for the pattern.
+44
+45
## API
+46
+47
### `(sigil json)`

+49
| Procedure | Purpose |
+50
|-----------|---------|
+51
| `json-encode` | Scheme value → JSON string |
+52
| `json-decode` | JSON string → Scheme value |
+53
| `json-read` / `json-write` | Port-based streaming I/O |
+54
| `json-get-in` | Path lookup into a decoded value |
+55
+56
See `docs/json.md` for full details.
