Fixed

• Fixed double-quote wrapping of already-quoted values during migration: migrateIfNeeded's line-by-line parsing preserved original YAML quotes, then re-wrapped with "..." — producing invalid YAML (e.g., key: ""<red>text</red>""). Now strips existing quotes via removeSurrounding before converting.
• Fixed &r producing invalid </reset> closing tag: MiniMessage's <reset> is a standalone tag with no closing counterpart. Now closes all open tags, emits <reset>, and skips adding reset to openTags.
• Fixed migration skipping YAML block scalar values (| / > multi-line values): legacy & codes inside indented lines after |- were silently ignored. Now detects block scalar indicators and collects+converts indented content lines.
• renameTo return value is now checked: when backing up lang.old.yml, if the rename fails the migration aborts with a warning instead of silently proceeding and risking data loss.
• MLang.readIntoCache now catches YAML parse exceptions: if migration produces invalid YAML or users manually corrupt the file, falls back to the default lang.yml from the jar to prevent plugin startup crashes.
• legacyToMiniMessage reuses class-level legacyPattern regex instead of redefining it inline.
