Repoint two firmware doc links at firestarter_fw
docs: point the firmware reference links at beta main is 525 commits behind beta on the firmware repository, so a link into main would not resolve for a long time. beta is where work actually lands. These resolve once firestarter#57 merges.
docs: put the logo on every page Five pages were missing the header block -- the ones written or rewritten during this pass rather than migrated from a repository that already had it.
docs: pin map headings lead with the chip, adapter section moved to the end Each pin map is now titled by the chip family it is for, with the layout reference in parentheses after it. The adapter section follows the pin maps rather than preceding them, since it applies to two families out of fifteen.
docs: restore the chip pin maps, lead protocols with their name Pin Maps carries all 15 chip family pin maps again. Moving them to the firmware repository was the wrong call: a pinout is what someone with a chip in their hand actually wants to look at. Only the shield's own wiring and control-register bits stay in the firmware repository, which is developer detail nobody programming a chip needs. Programming Protocols leads each section with the protocol's name and puts the number in parentheses after it.
docs: make the protocol pages user-facing Programming Protocols is now a plain description of what each protocol does and which chips it is for. Protocol ID and Protocol Flags are merged into it and deleted as separate pages. The implementation detail -- write algorithms, pulse widths, voltage routing, register constants, datasheet citations, the invariant matrix -- moves to PROTOCOLS.md in the firmware repository, linked from the top of the page. Pin Maps keeps the adapter wiring and the pin-21 warning a user acts on; the full per-family maps and shield wiring move to PINOUTS.md alongside it. Part numbers on the protocol page are now ones that actually resolve in the chip database -- the truth check caught W29C0xx filed under the wrong protocol, and several family prefixes and Dallas suffixes that were not real part numbers.
docs: cut the reference pages down to what a user needs Shield Revisions: replace the git-provenance inventory with a plain list of the real revisions and how to tell them apart. Drop the silkscreen alias table, the ADC band table and the investigation-history pointer. Capability matrix loses supported_protocol_ids, max_vcc_v and runtime_guard_gaps; notes now carry detection and jumpers. No modified or personal boards. Pin Maps replaces Pinout Safety Review and AT28C04 Adapter: socket pin maps for all 15 chip families generated from the pinout data, the DIP24 adapter reroute, and the shield's own pin and control-register assignments. Chip Database Fields replaces Infoic Field Dictionary: describes the Firestarter chip database rather than the upstream format. Protocol ID: protocol and what the algorithm is, nothing else. Protocol Flags: one bit/mask/meaning table, unknown bits included as unknown rather than guessed at. Package Details deleted -- its flags tables duplicated Protocol Flags and its own half was DIP-filter internals. SRAM and NVRAM Behavior deleted. Lockable PROMs keeps its family tables; intro tightened and tracking parameters stripped from the datasheet links.
