Add 152 missing release years across 11 platforms

Fills gaps in metadat/releaseyear/ for 152 games that had entries in
other metadat categories (genre/developer/publisher) but no release
year. All entries were matched to existing games by the ROM CRC already
present in the database — no new titles, no renames, no changes to
existing entries.

Coverage

  • Nintendo - Game Boy Advance — 41
  • Sega - Master System - Mark III — 29
  • Sega - Game Gear — 16
  • Sega - Mega Drive - Genesis — 15
  • Atari - Lynx — 14
  • Nintendo - Game Boy — 12
  • Nintendo - Game Boy Color — 8
  • Nintendo - Super Nintendo Entertainment System — 6
  • Bandai - WonderSwan Color — 4
  • SNK - Neo Geo Pocket Color — 4
  • Bandai - WonderSwan — 3

Sourcing

Each year was verified against two or more independent sources
platform-authoritative references (Sega Retro and SMS Power for Sega
systems; AtariAge and scanned manuals for Lynx; regional Wikipedia for
Japan-only WonderSwan titles) corroborated by a general source
(Wikipedia, MobyGames, GameFAQs).

The year is region-matched to the No-Intro name: (USA) → North
American release, (Europe) → European, (Japan) → Japanese; for
multi-region dumps like (USA, Europe) the earliest listed region's
year is used, consistent with existing entries in these files.

A few representative disambiguations:

  • Castle of Illusion (SMS/GG) dated to its 1991 8-bit release, not the
    1990 Genesis version.
  • Wario Land II (GBC) → 1999, the color re-release, not the 1998 mono
    original.
  • Faselei! (NGPC) → 2000 from the UK release, since the US release was
    cancelled.
  • Judgement Silversword (WonderSwan) → 2004 Qute retail cartridge, not
    the 2001 WonderWitch contest build.

Format / verification

Entries follow the existing file format exactly (tab-indented
comment/releaseyear/rom ( crc … ) blocks), inserted in the
files' alphabetical order. All 11 modified files were checked to have
balanced game ( / ) blocks with one releaseyear per game.

Fills releaseyear gaps for games already present in the database
(matched by existing ROM CRC): GBA 41, SMS 29, Game Gear 16,
Mega Drive 15, Lynx 14, Game Boy 12, GBC 8, SNES 6, WonderSwan Color 4,
Neo Geo Pocket Color 4, WonderSwan 3.

Each year verified against 2+ independent sources (Sega Retro, SMS
Power, AtariAge, regional Wikipedia, MobyGames, GameFAQs) and
region-matched to the No-Intro name (earliest region for multi-region
dumps). No new titles, renames, or changes to existing entries.

Not a reviewer, but just wanna ask did you manually verify them? Not condoning AI, but since it's a large commit, most likely AI has been used, and thus, a manual check might be necessary.
