feat: lobby + champ select polish — 9 new features

Lobby / Profile (block A):
- Daily summary: games played, W/L, winrate, streak, LP net, best KDA,
  and total time played today. Time turns yellow >3h and red >5h with a
  "consider a break" hint.
- Tilt gate: after 3+ ranked losses in under 2h, soft banner with personal
  historic winrate after 3-loss streaks ("drops from 48% to 31%").
- Champion-specific improvement: top 3 champions (≥3 games each) compared
  against the user's overall baseline on KDA / CS-min / Gold-min / WR
  with color-coded deltas.
- Game time threshold warnings (integrated into daily summary).
- Ban frequency tracker deferred — needs backend changes to store enemy
  champion IDs per past match.

Champion Select (block B):
- Comp callouts: analyzes ally team traits (engage / frontline / peel /
  scaling / burst) and surfaces strengths and gaps as color-coded chips.
- All-lanes matchup: per-position FAVORED/EVEN/UNFAVORED verdict for
  every ally-vs-enemy pair with early/late game deltas computed from
  power curves.
- Trinket recommendation: yellow / sweeping / blue based on role +
  invisible threat detection + ranged poke matchup heuristics.
- Build alternatives style labels: existing AltTabs picker now tags
  options as "Popular" (highest pick_rate) or "Best WR" (highest
  win_rate).
- Ward placement tips: per-role timeline of suggested spots, adjusted
  by enemy jungler archetype (ganker / farmer / invader). Text-based
  MVP — full minimap visualization deferred.

English localization:
- Translated all level plan strings (champ select timeline + overlay
  tactical chips) and TTS messages from Spanish to English. Internal
  state labels left as-is. Future i18n work can extract these to
  message files.

 - **Level-by-level plan** — 18-level timeline vs your lane opponent with a contextual action per level (e.g. "Lvl 3 trade", "All-in con R", "Farm lado opuesto", "R2 + obj"). Calculates per-level advantage from power curves + spike bonuses + ult-strength comparison, with hexagonal nodes pulsing on spike levels and color-coded categories (dominant / strong / even / careful / weak). Full coverage for all 172 champions. Hover any level to see a coach-style tip in the detail card

 ## Champion Select
 
-- [ ] **Synergy/comp callouts** — explicit summary of team strengths and gaps: "Strong engage (Maokai + Yone), missing sustain, consider Karma or Lulu".
-- [ ] **Skill matchup for ALL lanes** — predict each lane's matchup outcome, not just yours, with simple verdicts (favored / even / unfavored).
-- [ ] **Trinket recommendation** — yellow vs sweeping vs blue ward based on role + matchup + typical swap minute.
-- [ ] **Build alternatives by style** — show "most popular", "highest WR", and "off-meta strong" side-by-side instead of a single recommended build.
-- [ ] **Ward placement preview** — first-3-min ward placements per role and against the specific jungler (Mobalytics-style).
+- [x] **Synergy/comp callouts** — strengths and gaps from trait analysis (engage, frontline, peel, scaling, burst). Color-coded list under the damage comp bar.
+- [x] **Skill matchup for ALL lanes** — predicts each ally-vs-enemy lane outcome from power curves with FAVORED/EVEN/UNFAVORED verdicts and early/late deltas.
+- [x] **Trinket recommendation** — yellow / sweeping / blue based on role + invisible threat detection + ranged poke matchup heuristics.
+- [x] **Build alternatives by style** — runes/spells/items pickers now label each option with "Popular" or "Best WR" by comparing pick_rate and win_rate across alternatives.
+- [x] **Ward placement preview** — text-based timeline tips per role and enemy jungler archetype (ganker/farmer/invader). Map-based visual deferred — diminishing returns vs effort.
 
 ## Lobby / Profile
 
-- [ ] **Daily / weekly summary** — winrate of the day, net LP, MVP count, KDA peaks. Shown when the app opens. Engagement + motivation.
-- [ ] **Champion-specific improvement** — for top 3 champions, compare your CS/min, vision/min, KP against the Gold average for *that specific champion* (not aggregate role).
-- [ ] **Tilt / streak gate** — after 3 ranked losses in <2h, soft prompt with personal data: "your historical winrate drops from 48% to 31% on games after a 3-loss streak — consider a break".
-- [ ] **Game time tracker** — "you've played 4h today". Optional ceiling notification.
-- [ ] **Ban frequency tracker** — "you should ban X based on your loss patterns".
+- [x] **Daily summary** — games played, W/L, winrate, streak, LP net, best KDA of the day, total time played. Shown at the top of lobby.
+- [x] **Champion-specific improvement** — for top 3 most-played champions (≥3 games), compares KDA/CS-min/Gold-min/WR against the user's overall baseline with color-coded deltas.
+- [x] **Tilt gate** — after 3+ ranked losses in <2h, soft banner with personal historic post-streak winrate.
+- [x] **Game time tracker** — total time played today shown in daily summary, colored yellow above 3h, red above 5h with "consider a break" hint.
+- [?] **Ban frequency tracker** — "you should ban X based on your loss patterns". **Deferred:** requires backend changes (match_history doesn't currently store enemy champion IDs; we'd need to fetch participants per past match — 5-50 extra HTTP calls on initial load). Could revisit if local data proves insufficient.
