G1 steps 5-6: input prompts, bookmarks, downloads, Saved Pages

Browse Source 
Everything touching the network or the card is a job on the Gemini
task (a missing card can block 5 s, past the main loop's watchdog):
about:start is composed from /gemini/bookmarks.gmi and the Saved Pages
(by capsule, newest first); file:// opens a Saved Page; s, S, r, d, b
and downloads report one line to the URL bar, S with progress Toasts.

A Saved Page is the cached body with a first line "> Saved from <url>
on <date>": it shows as a quote and gives relative links their base;
inside one, links to other Saved Pages open the saved copy, others go
online or say "Not saved, and offline". Input prompts (11 masked)
request the same URL with the answer as its query.

Fixed on the way: re-wrapping indented lines rebuilt the text from its
rows, inserting a space where a long word had been cut; refreshing
loaded the whole Saved Page next to a TLS connection (heap down to 436
bytes), now it reads one line and every fetch checks the 55 KB floor.

## Gemini
The Gemini App browses Geminispace (docs/milestones/G1.md): Tab and Shift+Tab pick a link, Enter follows it, Back returns (to where the page was scrolled), Space pages down, `g` types an address. Certificates are trusted on first use; a changed one stops the page and asks.
On a page, `b` bookmarks it, `s` saves it to the SD card to read offline (a non-text file goes to `/gemini/downloads/`), `S` saves it with the pages it links to on the same capsule (up to 30). The start page lists bookmarks and Saved Pages; inside a Saved Page, `r` refreshes it and `d` deletes it. With a card, every page streams through `/gemini/cache/` so a large one arrives whole even with IRC connected; what doesn't fit in memory stays on the card.
## Development aids
`scripts/serial_log.sh [seconds] [command…]` records the serial output, and can send commands to the firmware first. For example, `scripts/serial_log.sh 30 short sleep:12 burst` sets short screen timeouts, waits 12 s, then sends a burst of Toasts.
