feat: search profiles, cover letters, discovery fixes

- Add search profiles (DB, API, settings UI) and wire into scorer/pipeline search terms.
- Add cover letter generation (service, job action, JobDetail UI).
- Align JobSpy Indeed country with country-level search geography when settings conflict; warn in logs.
- Infer country from search cities via inferCountryKeyFromSearchGeography (shared).
- Ignore extractor venv/storage and local data in Biome; ignore orchestrator/storage and JobSpy .venv in git.
- Vite: do not watch orchestrator/storage (prevents reloads during startup.jobs pipeline).
- JobSpy: document Python 3.10+ and venv setup in README/requirements.
- Onboarding and settings: local resume path handling, orchestrator .env.example for Vite.

+# JobSpy extractor (Indeed / LinkedIn / Glassdoor)
+
+## Requirements
+
+- **Python 3.10 or newer** (`python-jobspy` has no compatible wheels on older versions).
+- A virtualenv in this directory (`.venv`) is recommended.
+
+```bash
+# Example: Homebrew (Apple Silicon paths may use /opt/homebrew)
+python3.12 --version   # or python3.11 / python3.10 — must be ≥ 3.10
+
+rm -rf .venv
+python3.12 -m venv .venv
+source .venv/bin/activate
+python -m pip install --upgrade pip
+pip install -r requirements.txt
+```
+
+The orchestrator uses `.venv/bin/python3` when present, otherwise system `python3`.
+
+## Manual test
+
+```bash
+source .venv/bin/activate
+export JOBSPY_SITES=indeed
+export JOBSPY_SEARCH_TERM="software engineer"
+export JOBSPY_LOCATION="Toronto"
+export JOBSPY_COUNTRY_INDEED=canada
+export JOBSPY_OUTPUT_JSON=/tmp/jobspy-out.json
+export JOBSPY_OUTPUT_CSV=/tmp/jobspy-out.csv
+python3 scrape_jobs.py
+```
+
+Adjust env vars to match what the app passes (see `extractors/jobspy/src/run.ts`).
