* fix(mobile): truncate oversize markdown reads instead of failing them The desktop bridge refused markdown over a private 512 KiB cap with file_too_large, which reached the phone as a generic runtime_error that the reader discarded, so a 632 KB file showed "Couldn't load markdown". Reads now return a UTF-8-boundary prefix under one shared 2 MiB budget, marked truncated with the full byteLength and read-only. The phone shows the truncation like file tabs do and maps refusal codes to real copy, so an older desktop's refusal reads "File too large for mobile preview". Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb * test(mobile): pin that a truncated markdown read is never editable The read budget sits above the edit budget, so every truncated document is already read-only as file_too_large. Pin that ordering so a future budget change cannot make a prefix editable, and name the constant as the markdown preview budget, separate from the file preview's own. Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb * test(mobile): refuse saves from a truncated markdown read A phone holding a truncated prefix must not write it back; the 256 KiB save guard refuses it as file_too_large before any version check. The shared budget test shrinks to the ordering it pins and names the bridge test as the behavioural pin. Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb * refactor(mobile): tighten markdown truncation types and measure once The read truncation measures the document once. The disk fallback drops its truncated-only read-only text, which the status line never showed, and both truncation fields are optional there. A markdown doc's flag is only ever true, and the schema comment names the hook, not line numbers. Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb * docs(mobile): drop a stale disk-fallback comment Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb * chore: retrigger CI after #23675 landed on main Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb
