fix: Complete memory leak fix with shortcode context tracking 
The v0.4.1 fix was incomplete - shortcodes called get_*_data() methods
directly, bypassing the recursion tracking in get_post_data().

Changes:
- Added $in_shortcode_context flag to TemplateLoader
- Added enter/exit_shortcode_context() methods
- All shortcode render methods now enter context before data loading
- When in shortcode context, the_content filter is always skipped

This fully prevents infinite recursion when post content contains
FediStream shortcodes that would otherwise recursively render.

# Changelog
All notable changes to WP FediStream will be documented in this file.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## [Unreleased]
## [0.4.2] - 2026-02-02
### Fixed
- **Complete fix for memory leak** - v0.4.1 fix was incomplete
- Added `$in_shortcode_context` flag to TemplateLoader to track when we're rendering shortcodes
- All shortcode render methods now call `enter_shortcode_context()` before loading data
- When in shortcode context, `the_content` filter is always skipped to prevent recursive shortcode processing
- This prevents infinite recursion when post content contains FediStream shortcodes
## [0.4.1] - 2026-02-02
### Fixed
- **Critical memory leak** causing "Allowed memory size exhausted" errors in Twig's StagingExtension
- Root cause: `apply_filters('the_content')` in `get_post_data()` triggered shortcode processing, causing infinite recursion when post content contained FediStream shortcodes
- Added recursion depth tracking with `MAX_RECURSION_DEPTH = 3` to prevent runaway nesting
- Nested items now skip `the_content` filter, using `wp_kses_post()` instead
- Nested data loading (albums within artists, tracks within albums) is now properly bounded
### Changed
- Made `get_artist_data()`, `get_album_data()`, `get_track_data()`, and `get_playlist_data()` public methods in TemplateLoader (previously private but called externally)
- These methods now accept both `int` post IDs and `WP_Post` objects for flexibility
- Added `$load_nested` parameter to control whether nested items are fully loaded or just counted
