* fix(costs): read token usage from Claude Code transcripts instead of tmux

Replace tmux screen-scraping with reading token usage directly from Claude
Code transcript files at ~/.claude/projects/*/. This enables accurate cost
tracking by summing input_tokens, cache_creation_input_tokens,
cache_read_input_tokens, and output_tokens from assistant messages.

Adds model-specific pricing for Opus 4.5, Sonnet 4, and Haiku 3.5 to
calculate USD costs from token counts.

* fix(costs): correct Claude project path encoding

The leading slash should become a leading dash, not be stripped.
Claude Code encodes /Users/foo as -Users-foo, not Users-foo.

* fix(costs): make --by-role and --by-rig fast by defaulting to today's costs

When using --by-role or --by-rig without a time filter, the command was
querying all historical events from the beads database via expensive bd list
and bd show commands, taking 10+ seconds and returning no data.

Now these flags default to today's costs from the log file (same as --today),
making them fast and showing actual data. This aligns with the new log-file-based
cost tracking architecture.
