fix(cli): pad the kind column in search, callers, callees and impact

[sunerpy]

Summary

Two fixes found while publishing the website.

fix(cli): pad the kind column in search, callers, callees and impact

The human output of search, callers, callees and impact lays a row out as {kind:<12}{name}, which is
upstream's kind.padEnd(12) + name. NodeKind's Display wrote its name with write_str, which ignores the
formatter's width, so every row ran together. On the mini fixture, v0.53.2 prints:

functionadd
  src/math.ts:1
import./math

and impact prints functionrunDemo:3, fileapp.ts:1 and methodincrement:8.

NodeKind, EdgeKind, Language and ReferenceSubkind now format through Formatter::pad, which honours
width, fill and alignment and never truncates a longer name. Output written without a width (to_string(), the
JSON output, the index) is byte-identical, because pad with no width or precision writes the string as is.

test(store): give lock probes the caller's bound

The cross-process lock probes in index_lease and store_state_gates always tried the lock with SHORT_DEADLINE
(80 ms), whatever bound the caller passed; the bound only limited how long the parent waited for the child.

• The deadline is set before the child opens and validates the lock file, and acquire_file checks the deadline
  before its first try_lock.
• So on a slow runner, a probe of a free lock could report TIMED_OUT.
• Main's CI on c03fcbd (run 37135369551, attempt 1) failed exactly that way, in Windows Tests:
  current_writer_is_state_gated_retains_lease_and_stamps_the_exact_owned_value at store_state_gates.rs:1063,
  left: "TIMED_OUT" right: "ACQUIRED". The re-run passed.

The child now reads its lock bound from the parent:

• SHORT_DEADLINE where the lock is held and TIMED_OUT is expected;
• CHILD_WAIT where the lock is free.

The three index_lease probes that expected ACQUIRED under SHORT_DEADLINE now use CHILD_WAIT. No product
code changes.

Verification

• Red before the fix:
  • display_honours_width_and_alignment ("function|" instead of "function |");
  • search_human_result_line_pads_the_kind_to_twelve_columns;
  • text_rows_pad_the_kind_to_twelve_columns, which runs the real binary on the mini fixture: search,
    callers, callees and impact rows;
  • exclusive_probe_acquires_a_free_lock_from_a_slow_child and probes_acquire_a_free_lock_from_a_slow_child,
    which use a test-only 300 ms pre-acquire delay to stand in for the slow Windows child. Both reported
    TIMED_OUT for a free lock.
• Green after it.
• make pre-ci on the clean head 603286d (rustc 1.98.0): 4,365 Rust tests passed and 0 failed, 569
  frontend tests passed, docs-check OK, clippy -D warnings clean, archive smoke passed.

Document the new padded text rows

This establishes a byte-level human-output contract for search, callers, callees, and impact, but the commit leaves docs/cli.md unchanged. Document the padded kind-column layout in that canonical page so the public CLI behavior and its compatibility expectations are recorded alongside the implementation.
