feat(timers): ability reuse timers — Mend outcomes, Lay on Hands/Harm Touch, and two dead disciplines

[prokopto-dev]

Reported as "there is no automated timer for mend". Mend turned out to be
implemented and wired already — it just misses half of its outcomes — so this
also audits the rest of the long-reuse abilities and disciplines.

1. Mend fires on all four outcomes (fix)

The EQTool port matches two of Mend's four outcomes. The 6-minute reuse burns
on all four:

Outcome	Log line	Before
Success	You mend your wounds and heal some damage.	✅
Critical	You magically mend your wounds and heal considerable damage.	❌
Failure	You have failed to mend your wounds.	✅
Worsen	You have worsened your wounds!	❌

Note for the reporter: the two original lines were verified to work end-to-end
before this change, so if a plain success still shows no timer, the actual log
line is worth capturing.

2. Lay on Hands and Harm Touch (feat)

The two longest reuses a P99 character owns (72 minutes each) had no timer
in EQTool or here. New core/handlers/ability_cooldowns.py.

These lines name the target, never the user, so attribution is a guess and
a wrong guess strands a 72-minute row. Two gates, both chosen to under-detect
rather than over-detect:

• Class — only a paladin gets Lay on Hands, only a shadow knight Harm Touch.
• Direction — you harm-touch mobs and lay hands on people, so Harm Touch
  needs an NPC-looking target and Lay on Hands a non-NPC one. That discards the
  two common impostors: NPC shadow knights harm-touching the tank on aggro, and
  NPC paladins laying hands on themselves at low health. The self-target form of
  Harm Touch (You writhe in the grip of agony.) is never yours.

is_npc alone is not enough in either direction — it misses unnamed mobs
(a froglok knight) and matches plenty of ordinary player names (Bob is in
the master list) — so looks_like_npc pairs it with EQ's article convention.

Known residual: another paladin/shadow knight in view using theirs on the
same kind of target. Nothing in the line distinguishes it. The row dismisses
like any other, and a later You can use the ability ... again in line corrects
the countdown through DisciplineCooldownHandler. Flagging this explicitly as
the main thing to push back on if you disagree with the tradeoff.

3. Two disciplines that could never match a log line (fix)

Swept every * Discipline against the classes that can train it. 46 of 48
class/discipline pairs already worked across all seven discipline classes;
two were silently dead, each for a different reason:

• Puretone (bard 60) — its cast_on_you carries the file's trailing ..
  artifact. YouFinishCastingParser strips a trailing .. off the log line,
  so a .. in the data can never be the lookup key either way. C# normalizes
  exactly one spell (Defensive Discipline); extended to disciplines.
• Whirlwind (monk 53) — a later classless duplicate named Whirlwind
  claimed its message key first and the C# index guard then dropped the classed
  self-buff entirely. The trainable spell now seats at the head; the duplicate
  is demoted, not discarded.

Also corrects Harm Touch's recast to 72 min (the file says 30 s for both knight
abilities; C# only fixes Lay on Hands).

Deliberately scoped: ~80 spells carry the .. artifact, but 17 normalize
onto a message another spell already owns, which would move existing best-guess
matches. Kept to disciplines; the wider fix wants its own issue.

Verification

• 2014 passed (+~45 new), ruff clean.
• Drove the real app offscreen against a live log file — 10/10 scenarios,
  including the spell window rendering the countdowns and both impostor lines
  correctly ignored:

ok  Lay on Hands (pal)     window='… | You | Lay on Hands | 1:11:59'
ok  Harm Touch (SK)        window='… | You | Harm Touch | 1:12:00'
ok  Puretone Disc (bard)   window='… | Puretone Discipline Cooldown | 1:11:59'
ok  Whirlwind Disc (monk)  window='… | Whirlwind Discipline Cooldown | 1:00:00'
ok  NPC self-LoH ignored   rows=[]
ok  NPC HT on you ignored  rows=[]

Game data confirmed against the P99 wiki (Lay Hands,
Harm Touch, Mend).

Please merge with a merge commit, not squash, so the fix/feat commits
survive for semantic-release.

Changes requested. The Mend and discipline fixes look solid, and the full suite passes (2014 passed, 2 deselected). The new Harm Touch attribution has a false-positive path that contradicts its stated under-detection policy: common player names in the master NPC list are treated as NPC targets, so an NPC harm-touching such a player creates a false 72-minute timer for the active character.
