Initial scaffold + canonical Activity model
Context
-------
New connector suite that syncs UK brokerage activity (Trading212,
InvestEngine, Schwab email-parsed, CSV drop-folder) into Wealthfolio.
Lives outside finance/ intentionally — finance/ is untouched per the
plan at ~/.claude/plans/let-s-work-on-linking-temporal-valiant.md.
This change
-----------
- Poetry project with httpx, typer, bs4, dev tools (pytest, mypy strict,
ruff, yapf).
- Canonical Activity + Account models with the 6 UK tax wrappers
(ISA/SIPP/GIA/LISA/JISA/WORKPLACE_PENSION) and the 12 Wealthfolio
activity types from docs/activities/activity-types.md on the upstream.
- Validation invariants: BUY/SELL need qty+price, DIVIDEND/DEPOSIT/etc
need amount — raises early so providers can't silently emit broken
rows.
- to_wealthfolio_csv_row() shape matches Wealthfolio's CSV import;
primary sink path per the plan.
Test plan
---------
## Automated
- poetry run pytest -q → 7 passed in 0.03s
- poetry run mypy broker_sync tests → Success: no issues found in 4 source files
- poetry run ruff check . → All checks passed!
- poetry run yapf --diff --recursive broker_sync tests → no diff
## Manual Verification
Not applicable — pure data model, no runtime behaviour.
Closes: code-thw.1
