Add tally update instructions to release notes

Existing users can update with `tally update` instead of re-running
the install script. Show this option first since it's the common case.

fix: close temp files before parsing in tests (Windows compatibility)

On Windows, files can't be deleted while still open. The tests were
using `with` context manager but trying to delete inside the block.
Now properly close files before parsing and cleanup.

Add CSV export format for tally run output

Adds --format csv option to export transactions as CSV for use with
Excel, Google Sheets, pandas, or other tools.

Features:
- Transaction-level export with denormalized data (merchant, category, subcategory)
- ISO date format (YYYY-MM-DD) for proper sorting
- Tags semicolon-separated to avoid CSV comma issues
- Extra fields (paypal_merchant, apple_order_id, etc.) as additional columns
- Supports --category filter

Fixes #30

Add tests for quotechar and tab delimiter detection

- Test embedded delimiter in quoted field (verifies quotechar works)
- Test tab-delimited CSV detection

Improves test coverage for #70 fix.

Accept {*} as alias for {_} in CSV format strings (#61)

* Initial plan

* Fix CSV format parser to accept {*} as alias for {_} skip column

Fixes the issue where AI-generated configurations using {*} instead of {_}
to skip columns would fail with "Invalid format at column X: '{*}'".

Fix tag filter to match transactions, not merchants

Tag filtering was checking merchant.tags (the union of all transaction
tags) instead of txn.tags (individual transaction tags). This caused
all transactions from a merchant to appear when filtering by tag,
even if only some transactions had that tag.

Example: filtering by t:david showed all Amazon transactions instead
of only David's Amazon transactions.
