Make Favoritter installable as a Progressive Web App with offline
static asset caching and Web Share Target API for Android.
New files:
- internal/handler/pwa.go: handlers for manifest, service worker,
and share target
- web/static/sw.js: service worker (cache-first static, network-first
HTML) with {{BASE_PATH}} placeholder for subpath deployments
- web/static/icons/: placeholder PWA icons (192, 512, 512-maskable)
Key design decisions:
- Share target uses GET (not POST) to avoid CSRF token issues — Android
apps cannot provide CSRF tokens
- Manifest is generated dynamically to inject BasePath into start_url,
scope, icon paths, and share_target action
- Service worker served at /sw.js with Cache-Control: no-cache and
BasePath injected via string replacement
- handleShare extracts URLs from Android's "text" field as fallback
(many apps put the URL there instead of "url")
- handleFaveNew replaced with handleFaveNewPreFill that reads url,
description, notes from query params (enables share + bookmarklets)
- SW registration in app.js reads base-path from <meta> tag (CSP-safe)

Add an optional long-form "notes" text field to each favorite for
reviews, thoughts, or extended descriptions. The field is stored in
SQLite via a new migration (002_add_fave_notes.sql) and propagated
through the entire stack:
- Model: Notes field on Fave struct
- Store: All SQL queries (Create, GetByID, Update, list methods,
scanFaves) updated with notes column
- Web handlers: Read/write notes in create, edit, update forms
- API handlers: Notes in create, update, get, import request/response
- Export: Notes included in both JSON and CSV exports
- Import: Notes parsed from both JSON and CSV imports
- Feed: Notes used as Atom feed item summary when present
- Form template: New textarea between URL and image fields
- Detail template: Display notes, enhanced og:description with
cascade: notes (truncated) → URL → generic fallback text
