Feat request: add podcast RSS subscription management

[specter119]

Currently cliamp can play podcast RSS feeds via URL, but there's no way to save/manage subscriptions. Users need to remember and re-enter feed URLs each time.

Proposed solution:

Add a ~/.config/cliamp/podcasts.toml configuration file (similar to existing radios.toml):

# ~/.config/cliamp/podcasts.toml

[[podcast]]
name = "The Daily"
url = "https://feeds.simplecast.com/54nAGcIl"
# optional: auto-download new episodes
auto_download = false

[[podcast]]
name = "Lex Fridman Podcast"
url = "https://lexfridman.com/feed/podcast/"

Proposed UI:

1. New keybinding P to open Podcast browser (similar to R for Radio, N for Navidrome)

2. Podcast browser shows:

   • List of subscribed podcasts
   • New episode count (optional)
   • Last updated timestamp

3. In-browser actions:

   • Enter - load podcast episodes into playlist
   • r - refresh feed
   • a - add new podcast by URL
   • d - delete subscription

4. OPML import/export support (for migrating from other podcast clients)

Alternative: Minimal approach

If full subscription management is too complex, a simpler option:

# Just save feeds, no auto-refresh or episode tracking
[[podcast]]
name = "My Podcast"
url = "https://example.com/feed.xml"

With P key to browse saved feeds and load episodes.

I would love this feature as well. I would also like if podcast playback positions could be saved somehow so resume play could be possible. Sorry if this functionality already exists.
