fix: escape sed special chars in update_history to handle & in titles

[saschabuehrle]

Bug

#1576 — Anime titles containing & (e.g. "Panty & Stocking with Garterbelt") corrupt the history file, breaking the continue-watching feature.

Root Cause

In update_history(), the title is used directly in a sed replacement string:

sed -E "s|...|...${title}|" "$histfile"

In sed's replacement, & is a special character meaning "the entire matched text". So a title like Panty & Stocking with Garterbelt causes the entire matched line to be inserted where & appears, producing:

2	z3E78qds49jd4BSK9	Panty 1	z3E78qds49jd4BSK9	Panty & Stocking with Garterbelt (13 episodes) Stocking with Garterbelt (13 episodes)

This garbled line can't be parsed back, so history continuation fails.

Fix

Escape &, \, and the delimiter | in the title before passing it to the sed replacement string. The new entry path (printf append) is unaffected since printf "%s" doesn't interpret these characters.

Testing

Verified with titles containing &, \, and |:

• Panty & Stocking with Garterbelt → history line written correctly
• Continue-watching resumes from correct episode

Happy to address any feedback.

Works! Is there a need to escape | and \tho? I don't I have seen any anime with these in the title

Please bump the version

[saschabuehrle]

Fair point - probably overkill for anime titles. But | is the sed delimiter used in the same command so it would break the substitution, and \ is always dangerous in sed replacements. Figured it was safer to cover all the sed special chars while we are at it.

Bumped the version.

@Derisis13 this is a bit obnoxious, copying this to so many PRs.
We can integrate this into the PR template or into the CI system if this is important to you.
I can also draft a paragraph on our stance regarding AI usage in contributing.md

I bumped to 4.14.2, because I want to merge #1707 before this.
Also someone has to review this who feels a little more confident with regex, I'm too rusty
