fix: cookie methods actually work; session builds lazily (v0.1.7)

get_cookies() called filter_cookies() with no URL and always returned {}
for domain-bound cookies; now iterates the jar directly. set_cookie()
ignored path and leaked a shared cookie to every host when given a bare
domain string; scheme is now normalized and path honored, with
domain=None made an intentionally shared cookie instead of a silent
localhost-only no-op.

ExtendedSession also built its aiohttp.ClientSession synchronously in
__init__, which requires a running event loop under aiohttp>=3.14 and
crashed the common construct-before-the-loop-starts host pattern. The
session now builds lazily on first access, preserving the
_create_session subclass override seam used by aioweb_tls.

 ## Changelog
 
+### v0.1.7
+
+- **`get_cookies()` now returns real cookies.** Previously called `filter_cookies()`
+  with no URL, which only ever returns domain-less shared cookies — every normal
+  domain-bound cookie (including ones set by a real `Set-Cookie` response) was
+  silently omitted. Now iterates the jar directly.
+- **`set_cookie()` no longer leaks a shared cookie to every host.** A bare hostname
+  (`domain="example.com"`) built a schemeless URL, which aiohttp's jar treats as a
+  domain-less "shared" cookie sent with every request the session makes, including
+  unrelated hosts. A scheme is now added when missing so the cookie is scoped to
+  that host.
+- **`set_cookie()` now honors `path`** (previously ignored — the cookie always
+  landed at `path="/"`). `domain=None` is unchanged in meaning but now stores a
+  truly shared cookie (sent to every host) instead of one silently bound to
+  `localhost` only, which made `set_cookie(name, value)` (no domain) a silent
+  no-op for any real request.
+- **The backend session is built lazily**, not in `__init__`. Under aiohttp 3.14,
+  constructing `aiohttp.ClientSession` requires a running event loop; eager
+  construction crashed the common host pattern of attaching a session before the
+  loop starts (e.g. `bot.http = ExtendedSession(...)` in `Bot.__init__`). The
+  session (and any subclass's `_create_session` override) now builds on first
+  access instead.
+
 ### v0.1.2
 
 - Pinned `commons` to v0.2.1 (retry `attempts` floor fix).
