fix(seo): add canonical link to docs.html

[GeiserX]

Summary

• Add <link rel="canonical"> to docs.html pointing to https://declarenta.com/docs.html
• Fixes Google Search Console "Duplicada: el usuario no ha indicado ninguna versión canónica" warning

Context

The 3 "Página con redirección" entries are GitHub Pages mirror URLs redirecting to declarenta.com — expected behavior, no fix needed.

Summary by CodeRabbit

• New Features

  • Added support for importing Revolut XLSX files in multiple formats.
  • Enhanced wash-sale detection to use symbol-based matching when ISIN data is unavailable.

• Tests

  • Added comprehensive test coverage for Revolut transaction-log parsing and wash-sale edge cases.

📝 Walkthrough

Walkthrough

Adds Revolut transaction-log format XLSX parsing with multi-format detection alongside existing closed-positions support. Enhances wash-sale detection to use symbol-based grouping when ISIN is missing. Adds canonical link to docs page.

Changes

Revolut Multi-Format XLSX Parsing

Layer / File(s)	Summary
Data Models & Type Guards src/parsers/revolut.ts	New transaction-log format constants (TXN_DATE_HEADERS, TXN_TYPE_BUY/SELL, etc.), TxnLogColumns interface, and detection helpers (hasTxnLogHeaders, findTxnLogColumns).
Date & Currency Parsing src/parsers/revolut.ts	Enhanced parseRevolutDate to handle ISO 8601 timestamps; new parseCcyAmount utility to extract currency and amount from strings like "EUR 15.61".
Core Parser Implementation src/parsers/revolut.ts	New parseTransactionLog function parses transaction-log XLSX into trades, cash transactions, and open positions via position-accumulation logic. Updated parseRevolutXlsx to detect format and dispatch to appropriate parser (transaction-log vs. closed-positions).
Detection Logic src/parsers/revolut.ts	Updated detectRevolutXlsx and revolutParser.detect to recognize both closed-positions and transaction-log formats via header introspection.
CLI Integration src/cli/index.ts	Added Revolut XLSX detection and parsing block in parseAndMerge with broker naming and logging; adjusted detection order to check Revolut before eToro.
Tests tests/parsers/revolut.test.ts	Comprehensive transaction-log test suite covering detection, date/currency parsing, BUY/SELL trades, cash flows, open positions, edge cases (NaN/Infinity/blanks), and format coexistence with legacy closed-positions.

Wash-Sale Symbol Fallback

Layer / File(s)	Summary
Core Logic src/engine/wash-sale.ts	homogeneousKey now returns assetCategory:symbol (uppercased) when ISIN is absent, enabling wash-sale detection for non-ISIN assets grouped by category and symbol.
Tests tests/engine/wash-sale.test.ts	Added three tests: empty-ISIN trades block losses via symbol fallback; empty-ISIN trades with mismatched symbols do not match; CRYPTO asset category enforces 1-year window.

Canonical Link

Layer / File(s)	Summary
HTML Metadata src/web/docs.html	Added canonical link tag pointing to https://declarenta.com/docs.html.
