What does this pull request do?

Adds missing mob_skill_lists rows for Matamata skill list 275, covering one focused slice of #5494.

Evidence used:

• sql/mob_pools.sql assigns eight Matamata-family pools to skill list 275: Skittish_Matamata, Matamata, Emberflash_Matamata, Volatile_Matamata, Groundstomp_Matamata, Disturbed_Matamata, Sinewy_Matamata, and Apex_Matamata.
• sql/mob_skill_lists.sql had only the placeholder comment for 275 and no active rows.
• sql/mob_skills.sql already defines active Matamata skills 2965 through 2969: cranial_thrust, tail_thwack, embalming_earth, scalding_breath, and debilitating_spout.
• Existing LSB skill list 348 already uses those same five Matamata skill IDs.
• Public wiki family pages list the same Matamata-family TP moves.

This PR is not claiming packet-capture or retail-capture verification; it is a data-only correction based on current LSB data plus public wiki support. No proprietary client data, DAT files, packet captures, or private materials were used.

Steps to test these changes

Local checks run on Windows:

• Targeted static parser check confirming list 275 contains 2965,2966,2967,2968,2969 and all five referenced skill IDs are active in mob_skills.sql.
• PYTHONUTF8=1 bash tools/ci/sanity_checks/sql.sh sql/mob_skill_lists.sql
• PYTHONUTF8=1 bash tools/ci/sanity_checks/general.sh sql/mob_skill_lists.sql
• PYTHONUTF8=1 bash tools/ci/sanity_checks/python.sh sql/mob_skill_lists.sql
• PYTHONUTF8=1 bash tools/ci/sanity_checks/lua.sh sql/mob_skill_lists.sql
• PYTHONUTF8=1 python tools/ci/sanity_checks/lua_stylecheck.py test
• git diff --check
• Native MSVC/Ninja build using Visual Studio Build Tools 2022: passed after configuring build-msvc-cl with cl.exe.
• Temporary MariaDB 12.3 database import via python tools/dbtool.py update full: passed.
• DB query confirmed skill list 275 has the five intended skill rows and eight pools use list 275.
• python tools/ci/startup_checks.py: passed; all server processes reached ready to work.

Local limitations:

• PYTHONUTF8=1 bash tools/ci/sanity_checks.sh upstream/base was attempted, but timed out locally while running the Lua sanity phase. The targeted per-file sanity scripts listed above passed.
• A direct xi_test.exe run was attempted separately, but it exited nonzero before producing a clean final summary in this Windows session; CI should provide the authoritative full test matrix.

"no packet capture data was used"

Why?

[djjohnson13p]

Thanks, fair question. The wording was clumsy, so I updated the PR body.

I do not have a lawful retail packet capture for this slice, so I am not claiming packet-capture verification. The basis for the change is narrower: current LSB data already has eight Matamata-family pools pointing at list 275, active Matamata skills 2965-2969 in mob_skills.sql, an existing LSB skill list 348 using those same five skill IDs, and public wiki family pages listing the same TP moves. No proprietary client data, DAT files, packet captures, or private material were used.
