* fix: parse_inline drops links at position 0 and marks() loses href

Two bugs in inline link handling:

1. parse_inline(): Links at the start of a line (position 0) were silently
   dropped. The image-exclusion check `match.start() > 0 and ...` would
   short-circuit to False when the link started at position 0, causing it
   to be skipped entirely. Fixed by checking `match.start() == 0 or
   text[match.start() - 1] != '!'` instead.

2. marks(): All link hrefs were set to null. parse_inline() returns marks
   with the structure `{'type': 'link', 'attrs': {'href': url}}`, but
   marks() only checked `mark.get('href')` at the top level. Added
   fallback to `mark.get('attrs', {}).get('href')` to handle both
   the attrs-nested format from parse_inline and the top-level format
   used in the README examples.

Added tests covering both bugs plus regression tests for image exclusion.

* chore: verify pre-commit formatting

* fix: keep links at pos 0; preserve link href (no reformat)

* Render bullet lists as proper ProseMirror nodes in from_markdown()

from_markdown() stripped bullet markers (* / -) but emitted each item
as an independent paragraph node. Substack's ProseMirror editor expects
a single bullet_list node wrapping list_item children. Without this
structure, bullet lists render as disconnected paragraphs in the
published post.

Consecutive bullet lines are now accumulated and flushed as a single
bullet_list node with proper list_item > paragraph nesting. Non-bullet
lines and blank lines flush the pending list, so mixed content works
correctly.
