Maps Pi's lowercase tool names (bash, read, edit, write...) to
the capitalized form used by every other provider, so the
dashboard shows consistent tool names across providers and the
activity classifier works without extra lowercase entries.
Reverts the lowercase additions to classifier.ts since the
provider now normalizes tool names at the source.
- Adds support for Pi (pi.ai) as a new session provider.
- Pi sessions are stored as JSONL files under `~/.pi/agent/sessions/<project-dir>/` and use OpenAI-compatible model IDs (gpt-5, gpt-5.4, gpt-4o, etc.).
- `src/providers/pi.ts` (new): Pi provider - discovers JSONL session files, parses assistant turns, extracts token counts, tool calls, and bash commands, deduplicates via response ID with line-index fallback
- `src/providers/types.ts`: added bashCommands field to `ParsedProviderCall` so all providers carry extracted bash command lists
- `src/providers/index.ts`: registered Pi as a core provider alongside Claude and Codex
- `src/providers/codex.ts`, `cursor.ts`: added `bashCommands: []` to satisfy the new required field on `ParsedProviderCall`
- `src/parser.ts`: fixed bug where `providerCallToTurn` always emitted an empty bashCommands array instead of passing through the parsed commands
- `src/classifier.ts`: added lowercase tool name variants (bash, edit, read, write) to match Pi's tool naming convention in JSONL output
- `src/bash-utils.ts`: exclude `true`, `false`, and shell variable assignments from extracted commands; scan past leading `NAME=val` tokens so `FOO=bar ls` correctly records `ls` rather than being dropped
- `package.json`: added pi to keywords
- `tests/providers/pi.test.ts` (new): 16 unit tests covering session discovery, multi-turn parsing, tool/bash extraction, deduplication, zero-token filtering, and display name mapping
- `tests/provider-registry.test.ts`: updated core provider list to include pi
- [X] Unit tests pass (`npx vitest run`, 56 tests across 6 files);
- [X] Manually verified via `npx tsx src/cli.ts` report and showing Pi sessions alongside Claude and Codex in the dashboard.
