chore(toolchain): bump lance-graph to Rust 1.95.0 (baseline)

Aligns lance-graph with the rest of the AdaWorldAPI stack now that
ndarray master is on 1.95 (PR #145 merged 2026-05-13) and bevy was
already on 1.95 for edition 2024. Single rustc version across
{ndarray, bevy, lance-graph, MedCare-rs}.

Changes (baseline commit; lint fixes land in follow-up commits from
the sprint-log-8 fleet):

- `rust-toolchain.toml`: channel 1.94.1 -> 1.95.0
- 7 crate Cargo.toml `rust-version` "1.94" -> "1.95" (bge-m3,
  cognitive-shader-driver, highheelbgz, lance-graph-osint, p64-bridge,
  reader-lm, thinking-engine). `holograph` stays at 1.88. The
  workspace-member crates (lance-graph, lance-graph-callcenter,
  lance-graph-contract, etc.) don't declare rust-version explicitly.
- `.claude/board/sprint-log-8/MANIFEST.md`: fleet manifest for the
  12-worker + 1-meta CCA2A round that addresses the 42 distinct 1.95
  clippy lint sites surfaced after the bump.
- `.claude/board/sprint-log-8/lint_inventory.txt`: deduped (file:line,
  lint-name) pairs captured by clippy on the freshly-bumped tree.
- `.claude/board/sprint-log-8/clippy_1.95_full.log` and
  `.claude/board/sprint-log-8/clippy_1.95_deny.log`: full clippy output
  used to scope the fleet.

Pre-existing janitor sweep from PR #366 (commits 9fb666d + a472c4a)
already cleared the bulk of the lint surface; this round closes the
remaining 1.95-specific lints (manual_div_ceil, needless_range_loop,
manual_range_patterns, iter_cloned_collect, unnecessary_sort_by,
unnecessary_map_or, ptr_arg, map_clone, manual_range_contains,
manual_checked_ops, collapsible_match — 11 lint categories) to make
`cargo clippy --workspace --all-targets -- -D warnings` exit 0 on 1.95.

Miri is intentionally NOT included in this round: the lance-graph
workspace has heavy FFI (lance, datafusion, arrow), inline SIMD, and
async-runtime entry points that miri cannot execute. Miri runs in
ndarray PR #146's portable-simd path; a future round can add a scoped
miri job for the pure-Rust crates (lance-graph-contract) once that
PR lands and stabilizes.

Fleet runs in background; their lint-fix commits will follow.

+# Sprint-log-8 — lance-graph 1.95 bump fleet manifest
+
+**Branch:** `claude/lance-graph-1.95-bump`
+**Goal:** fix all 42 clippy lint sites surfaced after bumping rust-toolchain.toml to 1.95.0. The pre-existing janitor sweep in PR #366 cleared most of the surface; this round closes the remaining 1.95-specific lints to make `cargo clippy --workspace --all-targets -- -D warnings` exit 0 on 1.95.0.
+
+**Full error log:** `clippy_1.95_full.log` (80 warnings, no -D) + `clippy_1.95_deny.log` (with -D warnings, 64 error lines).
+**Lint inventory:** `lint_inventory.txt` (42 deduped sites).
+**Lint categories:** `manual_div_ceil` (6), `needless_range_loop` (5), `manual_range_patterns` (4), `iter_cloned_collect` (2), `unnecessary_sort_by` / `unnecessary_map_or` / `ptr_arg` / `map_clone` / `manual_range_contains` / `manual_checked_ops` / `collapsible_match` (1 each), plus rustc unused_imports/variables.

+- `(x + n - 1) / n` → `x.div_ceil(n)` (manual_div_ceil)
+- `for i in 0..N { v[i] = ... }` → `for (i, x) in v.iter_mut().enumerate().take(N) { *x = ... }` (needless_range_loop)
+- `0 | 1 | 2 | 3` → `0..=3` (manual_range_patterns)
+- `.iter().cloned().collect()` → `.to_vec()` (iter_cloned_collect)
+- `.iter().map(|x| x.clone())` → `.iter().cloned()` (map_clone)
+- `.sort_by(|a, b| b.x.cmp(&a.x))` → `.sort_by_key(|b| Reverse(b.x))` (unnecessary_sort_by)
+- `.map_or(true, |x| ...)` → `.is_none_or(|x| ...)` (unnecessary_map_or)
+- `&mut Vec<T>` → `&mut [T]` (ptr_arg)
+- `n >= 1 && n <= 7` → `(1..=7).contains(&n)` (manual_range_contains)
+- `if n > 0 { x / n }` → `x.checked_div(n)` (manual_checked_ops)
+- nested `if let` inside outer `match` → match guard (collapsible_match)
