fix(hooks): always mine the active transcript as convos, additive to MEMPAL_DIR

Browse Source 
#1230 fixed --mode convos for the case where MEMPAL_DIR was unset, but
left two configurations broken:

  - MEMPAL_DIR set to a project dir: convos never mined (MEMPAL_DIR
    overrode the transcript path); only project files were ingested.
  - MEMPAL_DIR set to a conversations dir per the old hooks/README: the
    projects miner ran on JSONL — same wrong-miner behaviour.

The shell hooks (mempal_save_hook.sh, mempal_precompact_hook.sh) had
the same MEMPAL_DIR-overrides-transcript bug AND were missing --mode
on every spawned `mempalace mine` call.

Make the auto-ingest *additive*. _get_mine_dir → _get_mine_targets,
returning a list of (dir, mode) pairs:

  - MEMPAL_DIR (when valid) contributes (dir, "projects")
  - A valid transcript JSONL contributes (parent, "convos")
  - Both can appear together; the hook spawns one ingest per target

Same change applied to the shell save and precompact hooks. Precompact
also gained transcript_path parsing so it can run the convos mine
synchronously before context is compressed. hooks/README.md updated to
describe MEMPAL_DIR as a project-files target, never a convos target.

- **`SAVE_INTERVAL=15`** — How many human messages between saves. Lower = more frequent saves, higher = less interruption.
- **`STATE_DIR`** — Where hook state is stored (defaults to `~/.mempalace/hook_state/`)
- **`MEMPAL_DIR`** — Optional. Set to a conversations directory to auto-run `mempalace mine <dir>` on each save trigger. Leave blank (default) to let the AI handle saving via the block reason message.
- **`MEMPAL_DIR`** — Optional **project directory** (code, notes, docs) to also mine on each save trigger, with `--mode projects`. The hook ALWAYS mines the active conversation transcript automatically with `--mode convos` — `MEMPAL_DIR` is purely additive, never an override. Leave blank if you don't want to ingest project files.
- **`MEMPALACE_PYTHON`** — Optional env var. Python interpreter with mempalace + chromadb installed. Auto-detects: `MEMPALACE_PYTHON` env var → repo `venv/bin/python3` → system `python3`. Set this if your venv is in a non-standard location.
