feat: add support for dubbed/subbed status in history

[HarshK97]

fix: remember dub/sub mode in history and resume correctly with -c

Type of change

• Bug fix
• Feature
• Documentation update

Description

This PR fixes an issue where the history mechanism (ani-cli -c) would not remember if the user was watching the dub or sub version of an anime, causing it to incorrectly default to sub when resuming.

Background

While using ani-cli -c, the CLI reads from the ani-hsts file which originally only stored ep_no, id, and title. Because mode (sub/dub) wasn't saved to history, continuing an anime would always use the globally set mode (which defaults to sub), forcing users to manually add the --dub flag every time they wanted to resume a dubbed anime.

What this PR changes

• ani-cli now securely stores the mode parameter (sub or dub) as an additional field in the ani-hsts history file.
• The -c interactive menu properly extracts the tracked mode and seamlessly restores the user's preference when fetching the next episode.
• The history prompt interface has been upgraded to display the tracked mode, showing a clear visual indicator like (dub) or (sub) alongside the title and episode number.

Testing

Tested manually:
Core feature

• ani-cli --dub [anime] → plays dubbed episode and records mode in history ✓
• ani-cli -c → correctly shows [Anime Title] - episode X (dub) in the menu and successfully fetches/plays dubbed episodes upon selection ✓

Regression

• Legacy history entries (from previous versions of ani-cli) load perfectly, reconstruct the title without issues, and default to sub ✓
• Normal subbed playback functions correctly and updates history with sub ✓

I don't like this.
Generally you're either a dub user or sub user.
You can alias ani-cli to be ani-cli --dub, the issue of whether to use sub or dub is orthogonal to history imo.
The history file format hasn't been changed in a long time and I'm not comfortable changing it for something this minor.

@Derisis13 what do you think about this?

[HarshK97]

The alias approach doesn't work for users who watch some shows dubbed and some subbed, the mode is per-show, not a global preference. History is meant to make -c frictionless, requiring manual --dub every resume is exactly the friction it exists to remove.

[port19x]

Yeah, I see that despite my reservations there is some value and so I'm deferring judgement to Derisis on this one

[Derisis13]

No breaking the history file. Not worth it at all.

I'm glad we're in agreement on this
