fix(pi): classify native skill loads as Skill, not Read (#588) (#590)
Pi and OMP have no dedicated skill tool: a native skill load is emitted as
an ordinary `read` tool call whose path points at the skill's SKILL.md (or a
`skill://<name>` URI in newer OMP builds). The parser mapped every read to the
Read tool and never populated `skills`, so Pi/OMP sessions over-counted Reads
AND always showed an empty "Skills & Agents" breakdown.

Detect these reads (basename === 'SKILL.md', or a skill:// URI), extract the
skill name (parent directory, or the URI segment), and surface the call as the
`Skill` tool with the name recorded in `skills` -- exactly how the Claude
parser represents a skill invocation. That both removes the Read over-count and
lets the shared classifier tag the turn `general` so the Skills & Agents
breakdown picks it up (populating a field the dashboard never received before).
The path is read from arguments.path with a defensive arguments.file_path
fallback.

Tests cover SKILL.md / skill:// / file_path detection, a non-skill read staying
a Read, and an end-to-end check that a parsed skill load reaches the classifier
subCategory that feeds skillBreakdown.

# Pi
Pi agent CLI.
- **Source:** `src/providers/pi.ts`
- **Loading:** eager (`src/providers/index.ts:9`)
- **Test:** `tests/providers/pi.test.ts` (336 lines)
## Where it reads from
`~/.pi/agent/sessions/` (`pi.ts:55-57`).
## Storage format
JSONL (`pi.ts:98`).
## Caching
None.
## Deduplication
Per `<provider>:<path>:<responseId>` when a response ID is present, falling back to the entry timestamp, and finally to a line index (`pi.ts:164`).
## Quirks
- Undefined token fields in `message.usage` are coerced to `0` (`pi.ts:156-159`); never `undefined`.
- The provider name is taken from `source.provider` (`pi.ts:182`), not hard-coded. This matters because `pi.ts` is the parser for **both** Pi and OMP; see [`omp.md`](omp.md).
- Tool-call content type is extracted from the message envelope (`pi.ts:169-176`).
- Pi/OMP have no dedicated skill tool: a native skill load is a `read` whose path points at a skill's `SKILL.md` (or a `skill://<name>` URI in newer OMP builds). The parser surfaces these as the `Skill` tool and records the name in `skills` (mirroring the Claude parser) instead of counting a `Read`, so the shared classifier tags the turn `general` and the Skills & Agents breakdown picks it up (`skillLoadName`, issue #588).
## When fixing a bug here
1. If you change parsing logic, also run `tests/providers/omp.test.ts` because OMP shares this code.
2. If the bug is "tokens are NaN", look at the coercion at `pi.ts:156-159`. A regression on this is silent and easy to miss.
3. If the bug is specific to the dedup behavior, decide which of the three fallback keys was used by adding a temporary log; the keys collide differently for old vs. new Pi versions.
