fix: symlog long/multi-byte symbol names no longer silently dropped (muse#61)

Symbol names whose percent-encoded form exceeded the OS filename limit (255 bytes) raised OSError inside append_symlog, which callers in commit.py swallowed silently — the journal entry was just lost with no visible error. Names over 200 encoded bytes now fall back to a hashed leaf name (marker-prefixed with '!', which percent-encoding can never produce), with a small per-directory sidecar index (.leaf_index.json) mapping the hash back to the original symbol name for list_symlog_symbols and list_symlog_symbols_for_file to resolve on read.
