feat!: callable-Pattern validator API + 223-pattern library across 22 category folders (#274)

Ships the callable-`Pattern` validator API and expands the built-in
library from 14 validators to **223**, organized into 22 category
folders.

## Callable-`Pattern` contract

Every built-in validator is now a `Pattern` instance whose `__call__`
returns `bool`. The old function-style `validator(value)` call form
still works; every `Pattern` method is now also available on each
validator (`match`, `to_regex_string`, `.explain()`, `.visualize()`,
etc.).

```python
from edify import Pattern
from edify.library import uuid, email

isinstance(uuid, Pattern)   # True
uuid("550e8400-e29b-11d4-a716-446655440000")   # True
uuid.match("550e8400-e29b-11d4-a716-446655440000")   # <re.Match ...>

email("[email protected]", strict=True)   # available on parameterized validators
```

Implementation:
- `Pattern.__call__(value) -> bool` on the base class (non-string
returns `False`, no crash on user input).
- **Every validator is built via the fluent chain** —
`Pattern().start_of_input().exactly(8).any_of()....end_of_input()`. No
raw-regex escape hatch anywhere in the library.
- Composable atoms in `edify/library/_support/atoms.py` (`hex_any`,
`octet`, etc.) keep the chains readable across categories.

## The 223 patterns across 22 categories

| Category | Count | Patterns |
|---|---|---|
| `identifier/` | 26 | uuid, guid, mac, ssn, ein, tin, itin, iban, bic,

url, uri, path, port, socket, ptr |
| `software/` | 13 | semver, version, package, docker, image, digest,
git, ref, checksum, component, makefile, cargo, bump |

alpha, numeric, word, unicode, emoji |

encoding, charset, locale, favicon, codec |
| `document/` | 11 | svg, pdf, epub, mobi, docx, xlsx, pptx, odt,

scientific, roman, ordinal, natural |
| `geo/` | 8 | coordinate, geohash, plus, postal, place, altitude, mgrs,

| `medical/` | 4 | medical, blood, dosage, dicom |
| `product/` | 3 | gtin, mpn, barcode |
| **Total** | **223** | |

Each pattern is importable both from its category submodule and from the
flat top-level namespace:

```python
from edify.library import uuid                     # flat
from edify.library.identifier import uuid          # category
```

## Merged and renamed 0.3 validators

Per the \"each pattern is unique / everything doable via a form must be
merged\" rule:

- `iso_date` → `date` (accepts every recognised date form)
- `email_rfc_5322` → `email` (accepts basic or RFC 5322)
- `ipv4` + `ipv6` → `ip`
- `phone_number` → `phone`
- `zip` → `postal`

+
+Upgrading from 0.3 to 1.0
+==========================
+
+.. _validators-callable:
+
+Validators are callable ``Pattern`` instances
+---------------------------------------------
+
+In 0.3 the built-in validators under ``edify.library`` were plain functions.
+In 1.0 every validator exposes itself as a :class:`edify.Pattern` instance
+that is *callable* — ``email(value)`` still returns a ``bool``, and the
+underlying pattern is available via ``email.match(value)``,
+``email.to_regex_string()``, and every other :class:`Pattern` method:
+
+.. code-block:: python
+
+    import inspect
+    from edify import Pattern
+    from edify.library import email
+
+    inspect.isfunction(email)        # False   (was True in 0.3)
+    isinstance(email, Pattern)       # True    (was False in 0.3)
+    email("[email protected]")        # True    (call form unchanged)
+    email.match("[email protected]")  # <re.Match object>
+
+The library is also reorganized into 22 category folders (``identifier/``,
+``address/``, ``contact/``, ``auth/``, ``financial/``, ``temporal/``,
+``geo/``, ``numeric/``, ``text/``, ``color/``, ``media/``, ``software/``,
+``transport/``, ``publishing/``, ``product/``, ``medical/``, ``api/``,
+``data/``, ``document/``, ``security/``, ``grammar/``, ``web/``). Every
+validator is importable both from its category submodule and from the
+flat top-level ``edify.library`` namespace:
+
+.. code-block:: python
+
+    from edify.library import uuid                    # flat top-level
+    from edify.library.identifier import uuid         # category submodule
+
+The library grew from 14 validators to **200 exported validators** across
+these categories.
+
+Renamed and merged validators
+-----------------------------
+
+Several 0.3 names have been merged into more general patterns in 1.0:
+
++---------------------------------+-------------------------------+
+| 0.3 name                        | 1.0 replacement               |
++=================================+===============================+
+| ``iso_date``                    | ``date``                      |
++---------------------------------+-------------------------------+
+| ``email_rfc_5322``              | ``email``                     |
++---------------------------------+-------------------------------+
+| ``ipv4``, ``ipv6``              | ``ip``                        |
++---------------------------------+-------------------------------+
+| ``phone_number``                | ``phone``                     |
++---------------------------------+-------------------------------+
+| ``zip``                         | ``postal``                    |
++---------------------------------+-------------------------------+
+
+The new names accept any recognised form of their concept, and the old
+name-plus-``form`` variants continue to work via each validator's
+``form`` / ``strict`` / ``version`` keyword arguments where applicable.
